|Aug 2026Terrible. Will not fly it again. Constant delays. Canceled flight because a pilot didn't show up the AA stated it was weather related. AA is also liars and didn't want to take responsibility or pay. Delayed luggage. Just horrible all the way around. Second time with this. Lost luggage on a previous flight. Back to Delta.
