I have a question. Can you see seat for international flight?
Currently, we have four people travel together, but 2 people seat on 33FG, another 2 people seat in 34AB. I called the UA agent a few time, everytime they said there are no seat open, they cannot put us seating together or back to back.

Any other way that I can login UA and see if seat is open up?

Thanks,
Lee
