Hi all -

I am flying out to SAN on business in October. Obviously, my company will not pay for first class, but I did manage to secure a B class fare. I am part of NW WorldPerks - so I know I can use those miles for upgrades.

Before I bought the tickets, I called CO to find out what flights had upgrade availability. Well, I could only secure an upgrade on the return SAN-IAH-BDL flight. Nothing on the BDL(no first)-EWR-SAN flight.

I doubt first is completely full, but rather they haven't opened anymore seats for upgrades (maybe I am wrong?). My question is - would it be worth it calling every so often up until my departure to see if anything is available?

Thanks!!!

Chris
