How long of a layover do you think is too long? I just got an email saying that the flights changed for our photographer and for FI's dad and they now have a 5 hour layover at 5 AM in San Francisco for their returning flight. I immediately got on the phone with the airline. The best they can do is reduce it to a 3 hour layover, as the earlier flight with the more reasonable connection was cancelled entirely.
What do you think?
