Hi - I was given a United travel discount coupon (10% discount) a couple of years ago when my flight was delayed. I am trying to use it now for a flight I am booking - when I get to the point in the online booking for the vouchers it is asking for a year issued and the name of the person the voucher was issued to - my coupon contains neither of these bits of information.
How do I go about using my coupon and do they expire? I looked and the T&C on the back of the coupon and do not see any reference to expiry dates.
I have emailed United but thought I might get a faster answer here.
