If a new resort opens, they may offer cheap airline tickets
Fly out at the right time. As with most of these search related parameters, turns out what we want the least is what makes the cheapest flight. The earlier your leave on a flight, the cheaper it will be. Red eye flights (in the middle of the night) are by far the cheapest, followed directly by early morning flights. Although you might luck out on a rare evening steal, typically the later in the day you depart, the more expensive your ticket will be.
Most major cities in the USA have reliable public transport options to transfer you to the city centres. For example, LAX has a shuttle bus ‘G’ to the Metro Green Line and JFK has the AirTrain connecting to the New York subway. Buses and taxis are also plentiful if you don’t want to negotiate traffic. However, in some cities hiring a car may be the quickest and convenient option to get around especially if you plan on doing a road trip. You’ll find all the major car rental agencies at most US airports, including Budget, Dollar, Hertz and Thrifty.
Compare between different airlines (regular and budget) and between the different classes of seats offered! If you can enjoy business class on a budget airline for the same money you'd pay to fly economy on a more "prestigious" airline, more power to you. You end up in the same destination but get to enjoy a more comfortable, luxurious experience. Why not?
Typically, I start all my searches with Momondo because it searches all major AND budget airlines, non-English websites, English websites, and everything in between. I’ve been using them since 2008 and they vet all the sites they link to as they have strict criteria on who the operate with. Momondo is one of the most comprehensive booking sites out there, they have the lowest price 99% of the time, and it’s the search engine all the other travel experts I know use too.

For Mozilla Firefox or Internet Explorer, hit Command (or “Control” if using a PC), Shift, “P”. This will open a new browser window where your information is not tracked, thus not inflating prices as you search.
