Hi,

To clear up some confusion...

I believe this is all on the same PRN. When I go onto BA.com and enter the record locator number, the entire sequence of flights appears.

I never said the flight was cancelled. The only message I got from her was that their departure was delayed and they wouldn't be getting home until Saturday. I assume that they didn't make it to the airport in time, or lines at the airport were unexpectedly long, or something else happened en route to the airport. She's traveling on a Overseas Adventure Travel trip (which also booked the tickets) and OAT provides transfers to and from the airports. Unfortunately, OAT isn't very helpful in trying to get her rebooked.

The authorized user thing...I just called BA, posed as her and added myself as an authorized user. So at least they're now willing to talk to me about her schedule. But they don't seem very helpful at getting her rebooked. I'm going to call them again right now.
