Just a quick one. I've got a JER-LHR booked on 11th. It's the evening flight and I'd like to go earlier in the day (but not enough to pay the current cost of the change, £150). I'm booked in economy plus so eligible for FCOD.

The earlier flights are already looking very busy (mostly Y0, one Y2, and that's about it). So there's a good possibility that I won't be able to FCOD at midnight. That said I doubt from experience that the flights will go out totally full. I don't live too far from JER (I suppose it's hard to live far on a small island...) so if I can't change at midnight, is there any value in going to JER and asking at the desk? Or will their answer always be the same as the published availability?
