May flights to the UK just dropped - ~$633 roundtrip after tax
I've been waiting for these ones to drop, May is the unofficial start of the Europe travel season.
And right on cue, Air Transat has dropped their prices pretty much exactly a month ahead of departure, to London (LGW) and Manchester (MAN).

There's actually one for $583 after tax, but that's a pretty short trip (May 14-19).
