Flying back from Mexico on Monday and we have discovered that it is old first. . . .
We are slightly disappointed, but the main question is, are we entitled to the compensation again. Just want be prepared.
Definitely -- talk to the CSD on the plane and he or she should add it into their iPad so that it processes for you. If that doesn't happen after about a week, send your details to BAMissingAvios (see my post a couple back).
How do you know that Monday's flight will be Old First? I've never been able to figure it out until the aircraft leaves LHR on the outbound.
