I ran into a couple of people selling vouchers (not in forums-no worries) who didnt know this so just as PSA - I am not sure if all United Vouchers are like this but it seems newer ones issued for complaints/delays etc. are redeemed in offer code box when booking (not gift certificate or travel voucher box when paying) and can only be 1) used for one person- cant combine two people on voucher and 2) are one time use only.
If someone knows how to get around this please let me know - especially annoying to have to book 2 seperate times for me and the mrs.
