Trying to combine credit card miles with airline
How can I book a trip using United airline miles combined with the Capital One card offering 50,000 Miles?
Use the Capital One card to pay for the taxes on an award booked with United miles and then use the CapOne rewards to redeem against the taxes and fees.
To expand a little on David’s statement. The “miles” you earn with Cap One are not traditional airline miles and they’re not even transferrable points like Amex’s Membership Rewards, Chase’s Ultimate Rewards or Citi’s Thank You Points.
Instead, you purchase some sort of travel with your Cap One card and use Cap One points to offset all or some of the charge. Like David said, you can use your UA miles for the major portion of the flight and then pay the taxes/fees with your C1 card. For some flights that won’t be a lot of money but for international flights in premium cabins that might amount to several hundred dollars.
The other nice thing about C1 points is that you can redeem them for other types of travel that airline miles/hotel points don’t cover, like cruises and tours.
Barclays Arrival points follow the same model as C1 and it’s really been helpful on some group tours I’ve taken.
