booked on united to Europe and flight severely delayed while checking in and put on LH. Once the ticket was changed at the United counter, went to apply the PP, it went to waitlist, went to check in, LH sees the waitlist, checked in, and 30 minutes later got cleared… which is best case scenario since the original UA flight was not going to clear anyways. I was pleasantly surprised.
This is a great data point. I wonder if it actually works essentially until boarding? Not planning to test it out though :-D
