Great service. Fast replies and the support was good. I was skeptical at first, but in the end I got the upgrade that I ordered.

Upgraded my United Mileage Plus account to Platinum in less than an hour. 10 minutes later I was able to upgrade four tickets to economy plus for free. Saved me a total of $1200 in upgrade fees! Couldn’t be happier. Excellent customer service. Will be using them in the future for sure.
