A couple of days ago it occurred to me I had a paper transportation voucher exchange coupon that I had not used. I have checked. It was issued in Nov19. Validity is 12 months. Should I assume this has now expired? Or did AA apply an extension to these vouchers? I can see that I could have probably booked forward travel before expiry and use covid exchange rules to try and use it but in the middle of it all I, and I guess a few others, just forgot about this.
