Holding upgrades
I just checked the system - I have a Caribbean flight in 42 hours. The coach has like three seats left, and the first class has 7 open out of 12.
There are SEVEN seats in first open, and they did not upgrade me yet. What are they waiting for? It's this mentality that is really going to get me to go to AA or NW. NW would have upgraded me three days ago!
Why bother offering the "5 day advanced upgrade" if they're not going to bother?
