My GUC cleared on 3 out of 4 flights and I'm on the waitlist flying out on the 13th. Seat map shows 22 empty seats but still no availability. Hoping it will clear before gate but if nothing before the 13th what do I do? Ask them at the check in counter? I don't trust the SCL Delta agents and if not on the list do I call DM line right there?

Thanks//
