So, why didn't I get the u/g during OLCI (which was the night before going to the airport)? Do you really think an F seat opened up in that time?
I wish I had more inside knowledge on how EUA works ...
I can think of a few possibilites:
1. There were a few seats left in the P bucket and it was close enough to the flight that the agent was allowed to give you one of those seats.
2. Someone that had a seat in the F bucket caught an earlier flight/cancelled etc, and that opened up that seat for you.
Check your account to see what class it shows you flew in (i.e. P/F/R) and that might give you an idea of what happened.
