I'm moving to England in October and I've been looking at flights for my move. I got a good chuckle when I looked at one way flights from LAX to LHR and they were almost $1800 My fiance told me to check the price of a round trip flight and they were $865! Needless to say we are going to go with the roundtrip flight and I will obviously not use the return leg, but what gives with those prices? Why so much higher for the one way vs. the round trip?? I'm completely clueless.
