Just finding this thread. Had a flight back on Oct 30th, FCA->SEA->LAS then on Nov 3rd the return trip. MVP

I noticed the waitlist opened up and I was never on it. This is the first time with airline status, so wasn't sure how it worked. Got to airport in SEA and asked gate agent. She confirmed I was NOT on the list, but did add my name. Looking at the fare class, O.

On the return trip, our names made the wait list, and I was auto upgraded on the SEA->FCA segment. Fare class G.

It was a bit frustrating not being on the list, probably put at end of lost, but then again there were like 30 people on list so unlikely to have been upgraded anyway. But I'll be sure to keep any eye out if I book into O class again.
