Citibank has launched a co-branded credit card with Czech Airlines. The Citi CSA card includes membership in the OK Plus frequent flyer program.

Two variants of the Citi CSA credit cards are offered. The standard Classic credit card awards one mile per 100 koruna spent, and the Gold card, two miles per 100 koruna spent. Both come with a welcome gift of up to 10,000 miles.

The Citi CSA credit cards maintain the same membership structure as the OK Plus cards. They are issued in three variants: OK Plus Member, OK Plus Silver and OK Plus Gold, depending on the number of miles flown or the number of flights taken.
