I recently used a Voucher to purchase a ticket (BWI-PHX). I dont think I will be able to use the ticket and now United is telling me that the Voucher amount will not be credited back to me (It was a Customer Service Voucher due to performance this summer) We used a $200 voucher on one ticket and a $50 on another. So now they are saying they are gone. That doesnt seem right or fair. I can understand the $75 change, but not the entire voucher amount.
