To follow up, it went fine. We told the ticket agent when we checked bags at our departure airport. She was a younger woman and was very confused, had to ask two supervisors what to do. So the pucker factor was high we'd get resistance and confusion the rest of the trip from Delta. But all the gate agents and FAs have been totally cool and it's been a smooth process. It's quite nice as others have said. I'm tall so it's nice to sort of sit diagonally.
