Upgrades
Has anyone ever noticed a difference (either way) in UG's on DL if they OLCI at T-24 vs. later vs. check in at airport?
Upthread, posters have discussed that they seem to get UG'd at the gate if at all, recently.
My flight is tomorrow evening SEA-SLC - we're at T-28.5 and two F seats still show unassigned (for what the seat map is worth).
