I don’t buy very many tickets, nearly everything I book is with miles.
If you cancel a ticket booked with United TravelBank funds you can request that you get a refund in the form of an electronic travel certificate valid for 2 years.
In the past I wasn’t able to combine TravelBank funds with an electronic travel certificate when redeeming for a ticket.
I’m not sure when that changed, but I was surprised when United.com allowed me to first apply $20 of expiring TravelBank funds and then apply $5.10 of an electronic travel certificate for the same ticket.
United.com looked like it was confused after I applied both of them, with all of it appearing to come from my TravelBank balance, but funds also saying applied from my electronic travel certificates:
However it successfully redeemed the correct amount that I entered from both balances!
Of course if I didn’t have status, but had a United credit card, I’d want to put a token amount on the card to take advantage of the credit card benefits. But with United status there’s no need to do that.
If you still have AMEX airline fee credit for 2020, go and buy some TravelBank funds before the promotion ends tonight!
