Here is my case: I bought tickets JFK-SFO with an American Express Platinum discount, and got a $200 credit to my card account, using their website. Now I must cancel because of the lockdown in the Bay area. I feel that if I call AmEx it will be a slow and painful process, and I probably cannot do it on the website. Can I cancel the flight on AA.com or by calling AA and get a flight credit ?
Then when I will rebook, will I have to deal with AmEx or can I call AA directly? AmEx is usually cheaper but I rarely get a knowledgeable and efficient agent.
