This might have already been asked, so sorry if reposting.
Post 4/15, what have experiences been with the following (on award ticket, where you are a MP credit card holder):
1) Book two award tickets together (one for yourself and one for a companion). Has your companion been upgraded with you at your window? Have you gotten companions upgraded at the airport when you missed the window upgrade?
2) Assuming you're a MP credit card holder. Have two award tickets with different PNRs. Has anyone succeeded in getting a companion on the separate PNR upgraded at the airport?
