I've read this entire thread, and I don't see the details for my situation. Perhaps, someone could comment.

On March 6, 2020, I bought a simple one-way domestic ticket for $140 on aa.com, to fly this Friday, March 27.

About 10 ago, I realized I would not take this trip because my event was postponed, and also the Covid-19 restrictions to stay-at-home, and avoid non-essential travel.

Rather than cancelling the flight for e-credit, I chose to wait for AA to cancel the flight, and possibly apply for a refund.

Today, March 25, I received an E-Mail from AA, stating that my flight was cancelled, and giving me two choices: accept a rebooking to another specified flight, or select another flight from a list of 13 flights. There was no option to cancel, either for a refund or e-credit.

I tried to submit a refund request at the refund screen, using my ticket number, but was told to first cancel my trip.

When I visit "My Trips", the trip has no Cancel button. It simply says "Your flight was canceled. We saved you a seat on a new flight", followed by the selection options mentioned above.

So, now, I'm puzzled. These seem to be my options. Please comment.

1. Telephone AA, wait on hold, and hope to resolve the situation.
2. Tweet AA, explain my problem, and hope for a reply.
3. Do nothing, and expect to receive an e-credit.
4. Select one of the offered flights, and hope that a Cancel button appears for the new "My Trip". Then Cancel the trip, and apply for a refund.

Thank you for any suggestions.
