http://www.click4sky.com is a new low-cost airline created by CSA Czech Airlines. Unlike most other low-cost airlines, Click4Sky does not operate any flights - instead it is being used as a marketing brand in order to sell unsold seats on existing CSA flights. In addition, the airline will sell all seats at a fixed price. Customers travelling with Click4Sky will experience exactly the same on-board service as those travelling with CSA.

Looks like all tickets are $100 (1990 CZK) all in, but a return ticket is required and only works in out of PRG
