Thanks All! Flight is made. It was remarkably quick and easy, which I did not expect, as I had a credit to apply. They said the call went to the Caribbean desk, (??). I couldn't completely understand the explanation through the accent. But the agent was patient with me and the exchange was very competently made and quicker and far easier than normal. Very good service. Now all I have to worry about is AA canceling flights Thursday out of PLS, depending on Dorian. Potentially cutting it close but nothing tomorrow except a handful of seats in Coach.
