Travel to Haiti doesn't give me a lot of options when it comes to airlines. My strong preference is to travel Air Canada (Toronto to Montreal to Pòtoprens), but Air Canada only flies once a week. So if I can't do a Tuesday to Tuesday flight, I'm usually stuck flying American Airlines (Toronto to Miami to Pòtoprens).
I can't say that I'm a frequent AA traveller. But I've come to the conclusion that a scary proportion of my AA flights involve some kind of screw up. Today they hit me with several annoyances one after another. And the net result is that I'm stuck in Miami over night. I hate Miami with the kind of white-hot seething hatred that I usually only reserve for Mike Harris.
