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.
A limestone spike rising dramatically from the emerald waters of Phang Nga Bay, James Bond Island (Koh Tapu — Nail Island in Thai) earned its moniker from appearing in two 007 movies: The Man with the Golden Gun (1974) and Tomorrow Never Dies (1997). Excursions depart from the popular resort areas of Phuket, Khao Lak and Krabi on photogenic longtail boats. On the tour, explore secret lagoons, craggy sea caves and a floating village.
Naturally, there are some amazing coral reefs for snorkeling and diving and pristine beaches (my favorite is Whitehaven Beach). Upon arrival, you’ll instantly see why this is one of the best tropical islands in the world — and why over half a million people visit a year. One of the most popular way to see the islands is via a multi-day sailing tour (which is what I did when I visited). It was an amazing experience — especially diving! Prices start around 450 AUD for multi-day sailing tours.

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.
