On any Star Alliance partner, you can redeem for Saver level awards on United via the partner site.

Avianca LifeMiles, Singapore, and Turkish are your options.

Avianca is probably the easiest to use (and I think the cheapest redemptions but search to be sure).

Note there is a $200 fee to get your points back if you cancel.

Make sure you check availability on the partner airline BEFORE transferring the miles!

I find Turkish Airlines is the best United partner that you can transfer Citi Thank You points to.

No, you can’t transfer directly transfer Citi Thank You Points to United Airlines.

You can transfer points to their Star Alliance partners.

I personally use Lifemiles.
