Called today because the domestic leg of my trip was showing PN2 and the first international leg had already cleared.
Asked if they could confirm the upgrade as inventory was available.
I was told it was only in the 72h timeframe that they could do an exception an confirmed an upgrade.
I re explained that it was showing PN2 so it was not an exception I just wanted them to clear the upgrade before someone else takes it.
She said that someone else must be before us on the upgrade list (which was doubtfoul because the flight was PN1 for a few days).
I told her to check because the flight was showing PZ1.
She ended up putting me on old and confirming the seats.
So much work !
