My flight leaves 36 hours, yet AA still send me schedule changes to the domestic part of my trip even though I know my international part of my ticket (onePNR) is canceled as it shows as such on the flight status AA website. However my booking is still showing as valid online, when i go into it. I have tried to apply for a refund but it says online that my ticket is not refundable, even though i know the flight is canceled and according to their website it is.
I read this on the DOT website.
"Airlines are required to provide passengers with information about a change in the status of the flight if the flight is scheduled to depart within 7 days. Airlines are required to give these status updates 30 minutes (or sooner) after the airline becomes aware of a status change. The flight status information must, at a minimum, be provided on the airline's website and via the airline's telephone reservation system"

I am wanting a refund as i don't know when or if, ill be in a position to travel again. Plus i got a great fare and it is unlikely when this is all over that i'll get one at that price again, ill probably end up paying thousands more being tied to an airline. I would rather have the cash. How long can i leave it before i call and ask for a refund. TIA
