Considering your interests (great food, hiking, beaches, nightlife unimportant) then Naxos should definitely be your other island. (And Naxos has many daily ferry connections with both Santorini and Athens.) Also, Athens needs at least one full day to explore so you should drop any thoughts about Delphi or Nafplio. Also, I would look into flights from Athens to Santorini on your night of arrival. If you could get to Santorini that night (and move your day in Athens to the end of your trip) you’d almost gain an entire day and could spend two nights on Naxos.
We’re planning a Greece trip to celebrate our 25th anniversary in September 2017 We plan to arrive in Athens and directly take train to Kalambaka/Meteora (2 nights), then down to Delphi (hotel stay in Athens), a day to see sights in Athens, a day trip to Nafplio and then leave to explore islands. Our plan is to go to Naxos for 4-5 nights, then to Santorini (for our anniversary) for 4 nights, and then to Crete for 5-6 nights. I would like to see Delos and wonder if it’s possible to stop in Mykonos, do the tour to Delos and still be able to catch ferry to Naxos the same day?
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.
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.

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.

Domestic air transport grew in China at 15.5 percent annually from 2001 to 2006. The rate of air travel globally increased at 3.7 percent per year over the same time. In the EU greenhouse gas emissions from aviation increased by 87% between 1990 and 2006.[75] However it must be compared with the flights increase, only in UK, between 1990 and 2006 terminal passengers increased from 100 000 thousands to 250 000 thousands.,[76] according to AEA reports every year, 750 million passengers travel by European airlines, which also share 40% of merchandise value in and out of Europe.[77] Without even pressure from "green activists", targeting lower ticket prices, generally, airlines do what is possible to cut the fuel consumption (and gas emissions connected therewith). Further, according to some reports, it can be concluded that the last piston-powered aircraft were as fuel-efficient as the average jet in 2005.[78]
Despite Zlarin’s small size and relative obscurity, it is certainly an island with dazzling beauty. It is known locally as the ‘Golden Island,’ because it’s really that eye-wateringly gorgeous! This small island is just off the mainland, separated by the Sibenik Channel and is mostly famous for its history of coral harvesting; there is even a Coral Museum where you can learn more about it.

My husband & I were planning to go on an organized Hiking the Greek Isles tour in May 2017, that we just found out is cancelled. It is our 10 year anniversary so we’d still love to plan a trip on our own for about 2 weeks in length. We are a bit apprehensive because we are from Canada and have never been to Europe before. I have several questions I’m hoping you can help me out with. One, how much should we budget/day for eating out for lunch & dinner? Most of the hotels look like they include breakfast. Two, how much should we budget for ferries? We are considering around 2 days in Athens, 2 days in Tinos, 2 days in Naxos, 3 days in Santorini & 4 days in Crete. Our main goals are seeing the beauty of the Greek islands, getting some physical activity in (walking & hiking), and spending time together. Any input would be much appreciated! Thanks very much!

As you head south, high-rise resorts give way to stretches of golden sand, such as Glystra, Tsambika, and Fourni. Inland, you'll find alpine forests (Mount Attavyros), hilltop castles (Monolithos), faded frescoes (Agios Nikolaos Foundoukli) and ancient ruins (Kamiros). Marooned on the southern tip, Prasonisi is a powdery peninsula where the Aegean meets the Mediterranean. One side is calm, the other choppy - a metaphor for this island of two halves.
Holding the largest number of overwater bungalow resorts in the world (more than 75 and counting), the Maldives understands its best asset is the gin-clear, abundant waters of the Indian Ocean. When you’re not snorkeling, diving, or gazing at the rich marine life through the floor windows of your water-top villa, continue enjoying the underwater display while dining at 5.8 Undersea Restaurant, or even while getting pampered in Huvafen Fushi’s submerged spa.
Since airline reservation requests are often made by city-pair (such as "show me flights from Chicago to Düsseldorf"), an airline that can codeshare with another airline for a variety of routes might be able to be listed as indeed offering a Chicago–Düsseldorf flight. The passenger is advised however, that airline no. 1 operates the flight from say Chicago to Amsterdam, and airline no. 2 operates the continuing flight (on a different airplane, sometimes from another terminal) to Düsseldorf. Thus the primary rationale for code sharing is to expand one's service offerings in city-pair terms to increase sales.
