My Thai wife and 3 children have a LAX to Thailand trip for 3 weeks on American. Given that the refund would be over $3,000, we would prefer a refund. So, we will try to wait until early June to see if the flight is canceled. A credit would be acceptable if we could get tickets with the same itinerary for July, 2021 for the same price. As I doubt if American would agree to that, I’ll go with my first option.
