Most of the time I've not had a problem (MAN-LHR, EMA-AMS and MAN-IAD), but sometimes they unexpectedly refuse. For example, in September I tried to book MAN-LHR for a Saturday morning next February, and was refused, which seems pretty odd. So I just bought cheapo tickets online instead.

When I asked about flights to Rome, they said no chance.

I'm about to try for two business-class LHR-YVR with AC for next September. What d'you think the chances are?

ps. The postman has been. Thanks!
