This error appears if the amount of the fare you selected changes during the booking process.

Possible reasons:

— some time has passed since the order was created, and the price has become outdated;

— the exchange rate in the booking system has changed, which led to the amount being recalculated.

In such a situation, you should refresh your search and start the booking process again.

The payment process for the order could not have started at this point and can no longer start, as the reservation with the outdated fare amount ceases to exist. Even if you have already entered your bank card details, you can be sure: no charge will occur, and your card details will not be saved.
