So I have a flight Friday night DTW-SFO, which means it's already within my upgrade window now. When I go to my seat map, the first class seat shows free, but when I select one, it never went through.
I called, the first agent tried to educate me my window starts from Monday, not 100 hours before, the "free" thing is an error.
The second one tried to charge me the fare difference to upgrade to first class, though there are upgradable spaces.
Anyone experience that before? I did have one exact same experience last year... thanks!
