American Airlines is horrendous.
Quick story....
Remember when wife and I lived in Fairbanks, Alaska--planned a Caribbean vaca--had a connecting flight in Dallas to Florida, ultimate destination was Jamaica. Anyway, our connection was really tight, and American didn't think we'd make it. They proceeded to sell our two first class seats to four different people!
We did make that connection, as runners (with carry-on only), wife and I boogied the mile+ to our terminal to be first in line! When two people, then two more, boarded the plane, came to first class and tried to take our first class seats, we told them 'hell no'.....compared booking dates for the flight attendant, our six-month-old bookings, compared to their hours-old tickets.
Parked our asses and wouldn't move and they couldn't make us. I did see a young serviceman walking by and told them that HE could have my seat, I'd take his. He politely refused and went back to coach.
After that we've never trusted AmA, complete snakes. An aside, wife is 10k miles short of her million with Alaska Air, a fine airline prior to the recent woke bullsh*t, she should have that million soon.
