Chances of Upgrade C to F on Z Fare?
Next weekend, going IAD-LAX, I'm taking the 777 in confirmed C on a Z fare and have a couple questions.
1. Do domestic three-class flights ever offer buy-ups at check0in through Mr. Chicken or on dot-bomb? I've read about it for Int'l, but wasn't sure about domestic.
2. What's the best strategy for maximizing my chances? Should I check in online or wait for the airport, and how far in advance?
Thanks in advance for the input.
