I found a reasonable ($517) last minute ticket for my mom SJC-LGW r/t via houston on CO.

Coming back, would she be able to ask to stand-by to SFO when she arrives at IAH? Would she have to do this before re-checking her luggage? Also, are there any payphones around customs/baggage re-check?

I have an unrelated question: on her outbound, she's on a flight that's arriving at 6 pm from SJC, and her flight to London leaves at 6:45. Will she have to run to make it?
