Does American offer upgrades at OLCI or the desk?
As per the title .... how likely is it that I will be able to pay for a J upgrade at check-in?
Does OLCI ever put forward an offer?
If I ask at the airport check-in desk will I be likely to have any luck?
This is for LHR --> LAX and this is the current availability:
