A complicating factor is that of origin-destination control ("O&D control"). Someone purchasing a ticket from Melbourne to Sydney (as an example) for A$200 is competing with someone else who wants to fly Melbourne to Los Angeles through Sydney on the same flight, and who is willing to pay A$1400. Should the airline prefer the $1400 passenger, or the $200 passenger plus a possible Sydney-Los Angeles passenger willing to pay $1300? Airlines have to make hundreds of thousands of similar pricing decisions daily.
The Ionian Islands are a quite different entity to the more familiar Aegean islands. There are in effect only seven of them plus a sprinkling of satellite islands that make for a very enjoyable package. They are different from the point of view of flora – they are greener and less barren than their Aegean cousins and they share a different history to the rest of Greece and the other islands, having absorbed much Venetian and Italian influences over the years. This is particularly apparent in the Old Town of Corfu where you could be forgiven for thinking you might be somewhere in Italy.
A group of 27 coral islands that form two atolls in the Indian Ocean, the Cocos Keeling Islands were virtually unheard of until beach activists Brad Farmer and Andrew Short named Cocos Keeling’s Cossies Beach as the best in Australia for 2017. Called the continent’s last unspoiled paradise, the remote destination is as special for what’s not there (high-rise resorts, chain restaurants, crowds, traffic) as what is — pristine white sand and a turquoise lagoon that’s home to 30,000 sea turtles.
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.
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. 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., 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. 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.
Lefkada is an island, but is connected to the mainland by a causeway at the northern tip and its access airport is on the mainland at Aktio (Preveza). It is an island popular with Greeks and mainly European visitors. Italians and Brits predominate. It is green, verdant, has good beaches and facilities and is compact enough to get around easily. Tourism is centred on the east coast around the port village of Nydri. It is low-key accommodation with villas and small family-run hotels predominating. Off-shore from Nydri are a couple of islands worth visiting on excursions: the sizeable Meganisi (car ferries run to and fro’) and the private Skorpios Island which belong to the Onassis family. On your own hired motor boat, you can heave-to on just one private beach on the north side of the island and swim and claim boasting rights to having swum on Aristotle Onassis’ private piece of Greece.
