Terrestrial based tracking using the time difference of arrival to calculate position. Should give high positional accuracy during most phases of flight, but position errors can sometimes occur. The ground speed is calculated and can sometimes be incorrect, especially during turns and at low altitudes. Vertical speed is also calculated, so errors can sometimes occur. Altitude data come from the transponder and should be correct. Read more 

The United States, Australia, and to a lesser extent Brazil, Mexico, India, the United Kingdom, and Japan have "deregulated" their airlines. In the past, these governments dictated airfares, route networks, and other operational requirements for each airline. Since deregulation, airlines have been largely free to negotiate their own operating arrangements with different airports, enter and exit routes easily, and to levy airfares and supply flights according to market demand. The entry barriers for new airlines are lower in a deregulated market, and so the U.S. has seen hundreds of airlines start up (sometimes for only a brief operating period). This has produced far greater competition than before deregulation in most markets. The added competition, together with pricing freedom, means that new entrants often take market share with highly reduced rates that, to a limited degree, full service airlines must match. This is a major constraint on profitability for established carriers, which tend to have a higher cost base.
We are planning to come back at the start of September for 2 weeks to visit different islands for some beach and sun. To give you some background, we loved Santorini, Milos and the quieter / smaller places in Crete (Loutro, Falassarna, Samaria Gorge). We enjoy beach time, some hiking, site seeing, good wine / food and good / buzzy atmosphere at night for dinner / tavernas.
Naxiots once made considerable fortunes exporting potatoes, cheese, marble and emery. Locals bequeathed undesirable seaside plots - useless for farming - to their laziest offspring. When tourists cottoned on to the island's scores of fabulous beaches, these wastrels found themselves sitting on gold mines. The west coast of Naxos is fringed with mile upon mile of powdery sands. Agios Prokopios and Agia Anna delight toddlers and teenagers alike with their shallow waters and beach bars. As you head south, the beaches get wilder: Plaka, where you can gallop across the dunes on horseback, Mikri Vigla for windsurfing and kitesurfing, and crystal-clear Kastraki.

Patmos has an indefinable je ne sais quoi - an otherworldly quality that radiates from its crowning glory, the medieval monastery of St John. This turreted fortress, bursting with Byzantine relics, is named after John the Divine, who conjured up his apocalyptic revelations in a cave nearby. Pure-white Chora, a World Heritage Site, is where A-listers and fashion editors stay. High walls and heavy doors conceal magnificent mansions dating back to the 16th century.
The advent of advanced computerized reservations systems in the late 1970s, most notably Sabre, allowed airlines to easily perform cost-benefit analyses on different pricing structures, leading to almost perfect price discrimination in some cases (that is, filling each seat on an aircraft at the highest price that can be charged without driving the consumer elsewhere).
My husband, another couple, and I are planning a trip to Greece in September 2017. We are staying in Milos for a few nights and were planning on staying at Melian Hotel and Spa….do you know anything about this hotel? I was worried about proximity to things, but it looks like no matter what, we are going to need to rent a car or use the bus system to get around. It seemed though that Melian had 6 or 7 restaurant options within walking distance. Also, any ideas or tips on things to do, see, or go?? We plan to do one of those semi private sailing tours, but other than that we are an open book. Thanks so much for any input!

The sleeper hit of the Cyclades, Serifos is the summer retreat of interior designers and architects who prefer to keep the sandy beaches to themselves. (One French home-owner is so protective of her hideaway that she tells all her friends she summers on nearby Sifnos.) Even in August, you’ll find coves where you can skinny dip in blissful solitude. That’s because the best beaches (Kalo Ambeli, Vagia, Skala) are only accessible via bone-rattling dirt roads or donkey tracks. Better still, rent a motor boat from the laidback harbour, Livada. Make sure to moor outside Anna’s taverna on Sikamia beach for freshly caught fish and garden-grown salads.
The Greek islands have beautiful weather in the months just before and after peak season. It’s a great time to see the islands, save money, avoid the crowds, and still have great weather (though not as hot as July and August). If you want to see the super-popular islands of Santorini, Rhodes, Corfu, and Crete without the tourists then this is a great time to visit.
Increasingly since 1978, US airlines have been reincorporated and spun off by newly created and internally led management companies, and thus becoming nothing more than operating units and subsidiaries with limited financially decisive control. Among some of these holding companies and parent companies which are relatively well known, are the UAL Corporation, along with the AMR Corporation, among a long list of airline holding companies sometime recognized worldwide. Less recognized are the private equity firms which often seize managerial, financial, and board of directors control of distressed airline companies by temporarily investing large sums of capital in air carriers, to rescheme an airlines assets into a profitable organization or liquidating an air carrier of their profitable and worthwhile routes and business operations.
The so-called pearl of the French Caribbean, Guadeloupe is a butterfly-shaped archipelago of five main islands where volcanoes tower and 200-plus beaches come in shades from black and white to red and pink. Basse-Terre’s tropical forest and the bay of Grand-Cul-de-Sac Marin were declared a UNESCO Biosphere Reserve in 1993. From there, island-hop to discover Grande-Anse beach on Les Saintes; Marie-Galante’s rum estates (and old-fashioned oxcarts); and La Desirade’s 900-foot plateau.
As soon as I think of travel, it’s not long before my mind drifts to white sand beaches, azure blue water, and palm trees in tropical locales. When most people think of paradise, chances are they’re thinking of tropical islands is far-flung corners of the world. Lounging with a good book, drinking from coconuts, soaking up the rays. Does it get any better than that?
The island’s next hotspot may be The Shore Club, the only development on Providenciales’ Long Bay Beach with 106 ocean view suites and six luxury villas on a nine-acre stretch. On popular, pristine Grace Bay Beach, Grace Bay Club’s tropical-chic redesign led by interior designer Thom Filicia includes redesigned lobby and guest rooms, the new Infiniti Restaurant and Raw Bar and The Residences, a trio of freestanding, beachfront villas. To get off the radar, the eco-conscious Sailrock Resort debuts this year on untouched South Caicos Island — secluded beaches are the buzz.
The almighty church has kept nightlife in check. If you must see and be seen, head to quietly glamorous Astivi or Stoa bar, on miniature Agia Lesvias square, in Hora. Beach life is generally languid and low-key; Psili Ammos and Livadi Geranou are our favourite hideouts. Dinner reservations are essential at Benetos, for Med-Asian fusion on an organic farm, and Lambi for grilled fish on a purple pebble beach. 

Little by little, though, Milos is being discovered. Instagram is saturated with no-filter shots of the undulating cliffs at Sarakiniko, the bottle-green swimming hole at Papafragas, and colourful, rickety syrmata, tiny boat houses wedged between rock and sea. (You’ll find the best photo opportunities at Klima and Mandrakia). This painterly landscape was shaped by the minerals that have long been a source of wealth – obsidian, alum, barite and sulphur, which still bubbles up in the island’s many hot springs. As the 11,000-year-old mining industry is gradually giving way to tourism, several chic hotels have made an appearance. Go now, before the trickle of visitors turns into a tide.
World War II, like World War I, brought new life to the airline industry. Many airlines in the Allied countries were flush from lease contracts to the military, and foresaw a future explosive demand for civil air transport, for both passengers and cargo. They were eager to invest in the newly emerging flagships of air travel such as the Boeing Stratocruiser, Lockheed Constellation, and Douglas DC-6. Most of these new aircraft were based on American bombers such as the B-29, which had spearheaded research into new technologies such as pressurization. Most offered increased efficiency from both added speed and greater payload.[32][33]
Every imaginable shade of blue manifests in the lagoon of Bora Bora, aka, the Jewel of the South Seas. Coral motus ring the main island like a sandy sash, and beneath the surface, dolphins, rays, sharks, turtles and colorful fish throng. Presiding over it all is the moss-green volcanic peak of Mount Otemanu, where god descended to the island on a rainbow, according to local lore. Timeless grass-skirted dancers and exotic overwater bungalows round out the sublime scene.
There are many picturesque villages to explore, and the beaches are always far from crowded. If you like walking, the lush vegetation and cliffs are ideal, while if you like to do some underwater exploration, there are many scuba diving and fishing opportunities, too. Additionally, Dugi Otok is home to one of Croatia’s best sandy beaches, Sakarun, which some compare to the beaches of the Caribbean, making it a great family spot.
That’s just the point. This craggy Cycladic island has always attracted loners, hikers, divers and pilgrims, who shuffle up the cliff face to the Monastery of Hozoviotissa, a sliver of white dangling 300 metres above the sea. The water here is a million shades of blue and so startlingly clear you can see every sea urchin lurking on the rocky shore. Even the sage-scented hiking trails are called Blue Paths, because the sea and sky are visible in all directions.
By the end of the 1930s Aeroflot had become the world's largest airline, employing more than 4,000 pilots and 60,000 other service personnel and operating around 3,000 aircraft (of which 75% were considered obsolete by its own standards). During the Soviet era Aeroflot was synonymous with Russian civil aviation, as it was the only air carrier. It became the first airline in the world to operate sustained regular jet services on 15 September 1956 with the Tupolev Tu-104.
Thank you for putting together such a great site. My husband and I are planning a trip to the Islands in May – neither of us have been and, honestly, have no idea where to even start putting together an itinerary. We have at least 14 nights to spend there (and may be able to push that to 17). I’m in my early 30s, my husband’s in his early 40s. Our priorities are culture and history, swimming, beautiful views, nice towns, and food and drink. We’re not interested in clubbing at all, but more laid-back late night bars definitely appeal. This is probably our one big holiday this year so while the budget is more mid-range than sky-high, we can push it a bit for the right places or experiences. We’re happy to take in quite a few islands, or with a mix of longer and shorter stays.

As a starter to explore ferry services, go to the Ferryhopper.com and punch in your route searches. Note: air travel between islands is not generally good. Air travel is normally only feasible between Athens (or other mainland destinations) and the island in question. Some exceptions do exist – Rhodes Kastellorizo, Kos-Leros-Astypalaia, Thessaloniki-Limnos-Ikaria etc. but again you will need bookings weeks in advance.
We’re on a budget (think €50 per person per day) and would like to go someplace warm and sunny where there’s also a combination of culture and nature. So we can explore in the mornings and relax at the beach in the afternoon. Preferably a sandy beach. We don’t need a lot of nightlife but it would be nice if not the whole island is closing down already. Do you have a suggestion?
I would recommend Naxos over Mykonos and with 12 days you could easily add Paros too. With Santorini, Paros, and Naxos you’ll get a good mix of different delights and some ferry island hopping too which is fun in itself. 1.5 days in Athens is perfect for most – 1 day for the Plaka, Parthenon, Acropolis Museum area; and a half-day to visit the Archaeological Museum which is a short drive or walk from the Plaka but hard to fit in one day along with the other sights.
Also heralded for its seclusion — as well as its beaches, diving, and mountainous beauty — is Indonesia’s Lombok, an island just east of Bali that one reader dubbed “Romance Island.” In fact, Indonesia seems to have the joys of island life down to a science, laying claim to the top three spots people most enjoy visiting. Read on for the full list of 15 winners.
Hey, sailors: In May, the 35th annual America’s Cup heads to the pink-sand beaches of the Great Sound, a prime time for racing enthusiasts. The event’s official hotel partner, The Hamilton Princess & Beach Club, transformed its “pink palace” with new guests suites, exhale spa, a state-of-the-art marina and three new restaurants including celebrity chef Marcus Samuelsson’s new venue, Marcus’. The upcoming Ritz-Carlton Reserve hotel and branded residences plan to open a mega-yacht marina in time for the race, but keep this island on your long-term radar: Michael Douglas and Catherine Zeta Jones break ground on the redevelopment of the famed Ariel Sands resort in 2017.
An airline is a company that provides air transport services for traveling passengers and freight. Airlines utilize aircraft to supply these services and may form partnerships or alliances with other airlines for codeshare agreements. Generally, airline companies are recognized with an air operating certificate or license issued by a governmental aviation body.

Known as the Cradle of Polynesia, Samoa is notable for its Fa’a Samoa way of life — a 3,000-year-old social code that prizes family, tradition and the environment. Happily, the landscape is as lovely as the local culture. On the main island of Upolu, a plunge into the To Sua Ocean Trench swimming grotto is a must. On Savaii, Samoa’s largest island, visit caves, waterfalls, blowholes and the Saleaula lava field, formed by a 1905 volcanic eruption that buried five villages.


My husband and I are heading to Greece in July this year. We fly into Athens and then are connecting to Samos where we are meeting up for a friend’s 50th birthday celebration. We have 4 nights here and then another week to explore some other islands. We would love to visit Santorini although I know it is not close to Samos so not sure if that is the best option? We thought about Paros or Naxos for 3nts, and then Santorini for another 3nts. Then fly back to Athens and spend a couple of days here before we head for Dubrovnik. Do you know if there are ferries between these Island points and would that be the best use of our time? I guess we don’t want to waste too much time travelling between points! We are just playing around with ideas at the moment as Samos is the only part set in stone. Open to any suggestions as this is my husband’s first trip to Greece and my last trip here was with my parents about 35 years ago!
In recognition of the essential national economic role of a healthy aviation system, Congress authorized partial compensation of up to $5 billion in cash subject to review by the U.S. Department of Transportation and up to $10 billion in loan guarantees subject to review by a newly created Air Transportation Stabilization Board (ATSB). The applications to DOT for reimbursements were subjected to rigorous multi-year reviews not only by DOT program personnel but also by the Government Accountability Office[46] and the DOT Inspector General.[47][48]
Located in southern Thailand, this semi-off-the-map island is one of my favorites and the month I spent here remains one of my most fond memories. Here on Ko Lipe, the super-friendly locals bring in the daily catch for amazing seafood, as the island’s water is teeming with life. Accommodation is still basic, and most places turn off the electricity around midnight.
What’s most stunning in Bali — dazzling beaches like Nusa Dua, Seminyak and Jimbaran Bay? Ubud’s terraced rice fields, sacred forest and ancient monuments? Or the island’s 10,000 intricate temples, including Pura Empul (the one you bathe in) and Uluwatu sea temple? Experience all of the above and decide for yourself. The Land of the Gods also boasts a loveliness that is more than skin-deep, thanks to its warm people and ubiquitous, inclusive spirituality.
Located in the middle of the Indian Ocean, the Maldives is a chain of 1,000 islands (200 are inhabited, and only 5 have any substantial population). The country is actually just a series of coral atolls that are barely above sea level. During the 2004 Tsunami, many of these islands were completely washed away. The government has built flood barriers to help lessen the impact of any future tsunamis.
Ultimately, the federal government provided $4.6 billion in one-time, subject-to-income-tax cash payments to 427 U.S. air carriers, with no provision for repayment, essentially a gift from the taxpayers. (Passenger carriers operating scheduled service received approximately $4 billion, subject to tax.)[49] In addition, the ATSB approved loan guarantees to six airlines totaling approximately $1.6 billion. Data from the U.S. Treasury Department show that the government recouped the $1.6 billion and a profit of $339 million from the fees, interest and purchase of discounted airline stock associated with loan guarantees.[50]
Fabulous site Dave! I am taking my daughter to Greece for 12 days in late May 2017 as a grad gift (yeah I know…, I think my Dad gave me a Timex watch, but I digress) and we are flying into Santorini expecting to spend 5-6 days there then ferrying over to Mykonos (not really sure why?) for a couple days. A couple days there and then flying into Athens for 2-2.5 days to inject some culture into what is otherwise somewhat hedonistic trip. I was wondering, after reading about other islands whether it is worth going to Mykonos. I’d love to go to Crete but it seems to be tough to squeeze that in. The original plan was to go to Istanbul for a couple days but it seems really sketchy right now. So is Naxos a better idea than Mykonos? Should we stay longer in Santorini? Is 2.5 days too much for Athens? Any and all info is appreciated.

The earliest fixed wing airline in Europe was Aircraft Transport and Travel, formed by George Holt Thomas in 1916; via a series of takeovers and mergers, this company is an ancestor of modern-day British Airways. Using a fleet of former military Airco DH.4A biplanes that had been modified to carry two passengers in the fuselage, it operated relief flights between Folkestone and Ghent. On 15 July 1919, the company flew a proving flight across the English Channel, despite a lack of support from the British government. Flown by Lt. H Shaw in an Airco DH.9 between RAF Hendon and Paris – Le Bourget Airport, the flight took 2 hours and 30 minutes at £21 per passenger.
Tinos is only 15 minutes from Mykonos, so it's a wonder it isn't overrun with tourists. The harbour is swarmed on 15 August, however, when Orthodox pilgrims flock here to kiss the icons at Panagia Evangelistria monastery, one of the holiest sites in Greece. Otherwise, the island is miraculously untouched. Solitary chapels and whimsical dovecotes stud thyme-scented hills, dropping to sandy bays whipped by the meltemi wind. There's a nascent surfer scene on Kolibithra bay, where a VW camper van has been converted into a cute beach bar.
Airline financing is quite complex, since airlines are highly leveraged operations. Not only must they purchase (or lease) new airliner bodies and engines regularly, they must make major long-term fleet decisions with the goal of meeting the demands of their markets while producing a fleet that is relatively economical to operate and maintain; comparably Southwest Airlines and their reliance on a single airplane type (the Boeing 737 and derivatives), with the now defunct Eastern Air Lines which operated 17 different aircraft types, each with varying pilot, engine, maintenance, and support needs.
Airlines follow a corporate structure where each broad area of operations (such as maintenance, flight operations (including flight safety), and passenger service) is supervised by a vice president. Larger airlines often appoint vice presidents to oversee each of the airline's hubs as well. Airlines employ lawyers to deal with regulatory procedures and other administrative tasks.[86]
Glad to see you mentioned the Cook Islands – my husband and I went to Rarotonga for a week in 2008 and fell in love with it – can’t wait to someday bring our kids back there – they would love it, too! Very few people have actually heard of the Cooks, or know where they are, and while I like the “secrecy” of it, I wish more people would visit! Currently there are only 1-2 flights/week from the US – makes planning trips there a bit tougher!We only took a day trip to Aitutaki because of time, but it was probably the most beautiful place I’ve ever been. Glad to see you agree!
Yes, I would agree that 8 or 9 days is too long for Naxos – unless you’re happy sitting at the beach for several of those days. But if you’re looking to be semi-active and explore then you’d be best to add Paros and spend 4/5 days on each. Crete, on the other hand, would be perfect for an 8/9 day road trip. Start in Heraklion (where the ferry arrives from Santorini) head east and then south and finally ending up in the western town of Chania where you can fly up home from.
India was also one of the first countries to embrace civil aviation.[54] One of the first Asian airline companies was Air India, which was founded as Tata Airlines in 1932, a division of Tata Sons Ltd. (now Tata Group). The airline was founded by India's leading industrialist, JRD Tata. On October 15, 1932, J. R. D. Tata himself flew a single engined De Havilland Puss Moth carrying air mail (postal mail of Imperial Airways) from Karachi to Bombay via Ahmedabad. The aircraft continued to Madras via Bellary piloted by Royal Air Force pilot Nevill Vintcent. Tata Airlines was also one of the world's first major airlines which began its operations without any support from the Government.[55] 

Growth rates are not consistent in all regions, but countries with a de-regulated airline industry have more competition and greater pricing freedom. This results in lower fares and sometimes dramatic spurts in traffic growth. The U.S., Australia, Canada, Japan, Brazil, India and other markets exhibit this trend. The industry has been observed to be cyclical in its financial performance. Four or five years of poor earnings precede five or six years of improvement. But profitability even in the good years is generally low, in the range of 2–3% net profit after interest and tax. In times of profit, airlines lease new generations of airplanes and upgrade services in response to higher demand. Since 1980, the industry has not earned back the cost of capital during the best of times. Conversely, in bad times losses can be dramatically worse. Warren Buffett in 1999 said "the money that had been made since the dawn of aviation by all of this country's airline companies was zero. Absolutely zero."[88]
DELAG, Deutsche Luftschiffahrts-Aktiengesellschaft I was the world's first airline.[1] It was founded on November 16, 1909, with government assistance, and operated airships manufactured by The Zeppelin Corporation. Its headquarters were in Frankfurt. The first fixed wing scheduled airline was started on January 1, 1914, from St. Petersburg, Florida, to Tampa, Florida.[2] The four oldest non-dirigible airlines that still exist are Netherlands' KLM (1919),[3] Colombia's Avianca (1919),[4] Australia's Qantas (1921),[5] and the Czech Republic's Czech Airlines (1923).[6]
Java, with a population of 140 million, makes its first appearance on this list. Celebrated for its ancient culture, breathtaking vistas, and UNESCO World Heritage sites like the Borobudur Temple Compounds, the island also offers the opportunity to indulge in modernity (five-star hotels abound). Waterfalls, volcanoes, protected parks, and white-sand beaches also allow visitors to get away from the thrum.
Airlines have substantial fixed and operating costs to establish and maintain air services: labor, fuel, airplanes, engines, spares and parts, IT services and networks, airport equipment, airport handling services, booking commissions, advertising, catering, training, aviation insurance and other costs. Thus all but a small percentage of the income from ticket sales is paid out to a wide variety of external providers or internal cost centers.
Drop-dead gorgeous Fiji is a filmmaker’s dream. Spy its Mamanuca island chain in Cast Away and Survivor; ogle its Yasawa archipelago in the 1980 version of Blue Lagoon. A dizzying amount of natural beauty — from mountains and mangroves to rivers and reefs — swathes Fiji’s 333 islands, and awe-inspiring wildlife (whales, sea turtles, dolphins, parrots) is the icing on the cake. For scenery with a side of luxury and exclusivity, reserve a bure (villa) at one of Fiji’s numerous private-island resorts.
