Check the prices for flights on this site - you can sometimes get better deals than on other airlines, particularly when booking short notice flights for Europe. Take a look even when you've looked at prices on a multi travel website such as Expedia or Travelocity - you may find a different and better deal here.
Once you've registered and logged onto this site you'll notice when choosing date options that there are different prices for different days and different prices for different flights on the same day depending on demand, usually the earlier you can book your flight the better, although they have some excellent special offers in low season.

Another cheap and cheerful airline (and a cheap and cheerful site) offering many special offers particularly to more unusual destinations such as Brescia, Carcasonne and Dinard. As with all of the budget price airlines you need to be very careful how much your bag weighs as you'll certainly be asked to pay extra if you're over the weight limit. Also there's very little food on board - you may want to take your own.
The no frills airline with a wide choice of flights to an increasing number of destinations. To get the best deals you need to be able to book ahead (and preferably be willing to get up early in the morning). There are some fantastic deals to be found here however the less flexible you are and the nearer your flight date the more likely you will be to find as good a price on another airline. It's always worth a check here, although the luggage constraints are tougher than on some other airlines and there's little food on board.
Virgin Atlantic will fly you to more than forty destinations from London including, in the USA, New York, Washington, Las Vegas, San Fransisco, Miami and Houston and also further afield to St Lucia, Johannesburg, Hong Kong, Havana and Tokyo. As always you should check the prices with the other major airlines servicing the destination you're looking for but this is well worth including on your search.
