Here's one for you to remember: airlines are under no obligation to fufill their side of the bargin. That is, if the plane is late or cancelled you have no recourse in practical terms. They don't have to give to your money back.

All they have to do is, at some point, give you the choice to take a later flight.

That's like saying. if you have movie tickets and they cancel the movie, they only give you another ticket. What if you are leaving town? You bought tickets for that movie specifically.

Tough luck.
