Anyway I can tell who is operating KL 642 tomorrow ? It's officially KLM but they don't let check in or choose seats since operated by another carrier. Delta sent email to check but also couldn't complete check in since operated by another carrier ?
Had the same thing last week. very weird.
Checked in on KLM, and seat selection was on DL. but seatmap couldn't load. Operated by Delta, but checkin in airport was at klm counter.
Couldn't do upgrade, cuz only Dl can do it.etc.
