Not a bad affiliate program (worked directly). But it works in it's own directions and only where the taxi price is close to the real price. For example Vilnius... I've already written to the support team that the prices are enormous. The airport is actually in the city. No traffic jams. Even if you just take a taxi on the front line, you'll pay a maximum of 15-20 euros. In the "discounted" system, the price is 30 euros.
