So I am due to fly out in around 36 hours. I am not in a position to accept a voucher and would like a refund (aa flight) . My booking is still showing as “ticketed” not cancelled. I know my flight is cancelled as it’s shows on the airlines “flight status” check page. They have since this time sent me confirmation of my itinenary. My question is, at some point, and when, are they obliged to cancel my booking. Until then I cannot request a refund. TIA
