AA is currently having some kind of system glitch in which a ticket from JFK- cities in Europe or Europe to JFK is coming out very very cheap. Ex. JFK- LHR on Feb. 15 is $59 plus tax of about $100!!!!!
However the catch is you can't book a one way flight at those cheap rates, you need to book a RT ticket to get the great one way fares. And they make up for it by charging much more on the return so that the RT price is nothing special, for example JFK- LHR Feb15. returning Feb 26 total price $723.90 AI.
I may have come up with a way around this though: book the outbound flight (which is the cheap fare) in regular lowest fare coach, then book the expensive return in Economy flexible which allows you to cancel the flight w/o any fees. Then cancel the return trip (free of any charges) and you have a OW to Europe for about $150 or so!!!
Is this going to work?
