Just booked flights for myself and my SO last night. Since I had an e-cert to burn, I booked us on seperate PNRs. Used my MP CC, which is stored on united.com. Her PNR is fine, but mine says I have to present the CC? Seems pretty strange.

Not that it is a problem, as I do carry the card with me normally, but I have to wonder why such a thing would happen?
