First segment economy, Second segment First -- what checkin, security, ...
As anyone ever had a first class leg of a flight after a coach leg of a flight on United? I am traveling with someone who didn't book first for the whole trip but has upgraded the second leg of the trip to first class. I am not sure if she can use the Premier Access check-in and security line when we check in for the flight because she will be in coach on the first flight. I am booked in first for the whole trip.
Has this ever happened to anyone?
