Thanks, everyone.
I've already done one round of 100K in Asia, flying CX, BA, CP, QF and AY. I did befor-check-in registrations and all of them were prited out at check-in. And all of them were posted just fine and got the first 100K with AA. I didn't know a case like Gabriel's could happen ...
I thought it would be a lot easier than faxing everything post-flight.
Let me see what will happen ... I'm starting a 12-segment trans-Siberian, trans-Atlantic, trans-Pacific RTW in four days .... from Sat. through Tues.
