I don't have any status. I'd be fine with two pairs, but what made me a bit worried was that even after selecting seats through customer service, at the checkin we had been moved to 4 single seats, even as our PNRs are 2 by 2. Well, I think we got seats like 20A and 21A, but that's not "together" for me.
So paying to choose seats in advance will secure them more firmy than calling CS 24hrs before the flight? Is there a way to do the checkin and secure the seats at T-24 with the 2 PNRs, if I find available seats together at that time?
