Flight on 05/05 from PRG > AMS was cancelled by KLM on 4/18 and then auto rescheduled to a earlier time. Submitted cancellation request on 04/19 for indicating flight was cancelled and clicked refund and back onto credit card.
04/21, the booking of revised time and prior flight both show cancelled and no longer a active booking. Didn't get any email or anything indicating. Curious to see what I get from Air France, I would prefer a full refund ideally. If I did a get voucher, I prefer getting the one that would refund you if the voucher wasn't used within a year versus the one where it was non refundable if not used.
Book through Airfrance US.
