Just landed in MIA from PTY today (connecting to DFW) and the wife and I experienced something odd at the gate in PTY. We had upgrades requested and were both on the same PNR but only one request came through and it was for me. I did decline because I did not want to be separated from my wife but I thought the policy was that two seats would have to be available at the same time for the upgrade to go through in the first place. Secondly, the gate attendant insisted that I would not be charged the stickers since I did not actually fly the seat but the ticket had already been printed and she had to switch me back. Should I be OK?
