Hi I didn't find a thread with this particular problem.

I originally booked a short haul economy flight to Hamburg through Amex Travel and selected the fare option with baggage. When I checked the booking on MMB at the time it showed the correct luggage allowance i.e. 1 bag - 23kg which should give me 2 bags since I'm Silver.

BA then cancelled the inbound flight and Amex rebooked me on a BA flight a few days prior to the original travel date. My Amex receipt for the revised booking still shows that it includes luggage but now it shows up on MMB as a hand baggage only fare. I don't want to have to have a discussion with the check-in staff at 5:30 am over whether I need to pay for 2 bags and at the moment BA aren't taking calls that don't involve changing reservations etc. Should I be worried about this?

Any insight is appreciated
