Southwest doesn't allow you to book ahead of time early enough for you to encounter too many schedule changes. American does have schedule changes, if you book early, so perhaps you've been lucky. Paying a little more won't help with this: What would help is buying airline tickets a little later (living with the uncertainty about what airfare will be available at that late date).Aimeedyan said:We usually fly SWA or American and never have issues. I'd rather pay a little more than deal with the constant changes.
