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. Valid date format: two-digit day, two-digit month, then full four-digit year, each separated by a forward slash or space. Example, enter 21 space 09 space 2016 to represent September 21, 2016, or 01/08/2016 to represent August 1, 2016. Alternately, use arrow keys to move through dates in the calendar grid.
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.
Those are 3 great islands. Corfu is much more green than Crete and Santorini and does have a different feel (more Italian but it’s no where near Turkey). The trouble with doing all 3 is that Corfu is on the opposite side of Greece from Crete and Santorini so you’d need to fly via Athens. It’s better for most people to visit another Cycladic island (Naxos, Paros, Milos, Folegandros) instead of splitting up their trip between the two sides of the country.
U.S. citizens don’t need a passport to explore this trio of Caribbean islands (St. Thomas, St. John and St. Croix). While the 133-square-mile chain has history in spades — Christopher Columbus touched down in 1493 — 2017 marks a banner year as the USVI celebrates its Centennial, with special events (festivals, parades and presumably lots of rum cake) continuing throughout the year. Also historic, Caneel Bay, the 60-year-old, 170-acre escape in St. John’s Virgin Islands National Park founded by environmentalist and preservationist Laurance Rockefeller, just celebrated its diamond anniversary. The property is bringing back the original beauty of its pared-down, 1950s-inspired Scandinavian style.
Nine weeks in Greece is a dream itinerary it certainly gives you lots of flexibility. As you seem to have Athens and the Peloponnese sorted, you just need to sort out your five weeks on the islands. What you need to realize, however, is that the islands are not all mutually interconnected, but rather they are ‘grouped’ – both administratively and from the point of view of transport routes. Here are the main groups.
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] 

Located just off the coast of Western Sahara in Africa, the Canary Islands are actually a Spanish archipelago and therefore owned by Spain. There are 7 main islands in the Canaries, with each offering something different for the intrepid traveler looking to kick back and enjoy island life. Tenerife is the largest of the islands and has a bit of everything, including one of the largest Carnival festivals in the world each February.

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.
