Hey folks, I'm doing GLA-LHR-MUC tomorrow with checked luggage. I checked in online fine for the GLA-LHR segment, but the LHR-MUC was rebooked onto LH a few weeks back due to a cancellation, and I can't checkin online, either with BA or LH. It's 125 ticketed. Do I just have to show up at the GLA bag drop and get them to sort it out there?
