A second financial issue is that of hedging oil and fuel purchases, which are usually second only to labor in its relative cost to the company. However, with the current high fuel prices it has become the largest cost to an airline. Legacy airlines, compared with new entrants, have been hit harder by rising fuel prices partly due to the running of older, less fuel efficient aircraft. While hedging instruments can be expensive, they can easily pay for themselves many times over in periods of increasing fuel costs, such as in the 2000–2005 period.
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.
