Flights To Houston

Does anyone know how to get free (or at least very cheap) flights to the U.S. from London? I've heard of mail theft or stand-by, but am not sure how to sort.
(Thanks in advance for not wasting my time with "hello-jacking," jokes!)

Check kayak.com .... this will give you a good idea of what the cost will be. You talk about Travel International, in London! I do not know such a thing as cheap, not to mention freedom still exists. Unless you have a friend or know someone who works for the airlines ... then you might be able to get an agreement.

FREE? uh ... no free lunch ... more not even the employees are free to ride ... taxes or a nominal fee still apply to them too. Marry an airline employee and there you have your free (or cheap) flight.
