Excellent point; wish I had! (But agreed to switch seats 3 times to let others sit together, as many seemed to be doing, and just lost track of the seats). I think that, having paid for the ticket with a cc in my name, that matches the passport, and having boarded and taken the flights, I would not have gotten so much c*** from United. They make it very difficult to get the miles credited, and I'm about ready to throw in the towel (which is exactly what they want and expect and hope for, I'm sure)...
