Just got a gift certificate that I want to use on an international flight. When I paste the gc number into the appropriate field, I always get the following error message:
! united.com was unable to validate your Gift Certificate at this time. Please try again later. If the problem persists, contact united.com Support at 1-800-396-1751 for assistance.
Is there any way to resolve this apart from calling? The certificate I am using is only a few days old and I can verify the balance successfully...thanks in advance for any tips you have!
