I think my record for negative experiences definitely is owned by Delta... holy shit I can't even add up the number of instances where they have royally screwed me. Little experience with United, have only flown them a number of times... AA while not great is the go to out of MIA for me here and while I have never been impressed; they've never actually screwed me.
