Be very careful and avoid the portal lastminute.com because they use a very dirty way of doing business. When searching for the best flight price on the Skyscanner portal, the best flight price and conditions were found on the lastminute.com portal. I selected the link and started the process of paying for the plane ticket, but after entering the credit card information and confirming the payment, the moment I pressed the "confirm" button, the price increased by 20%. Of course, the transaction authorization process cannot be stopped and the transaction is approved. I immediately called my card company and asked to cancel the transaction, but unfortunately, it was not possible. After that, I called lastminute.com's customer service and got the answer that I can get a refund minus the transaction cancellation fee or a voucher for the same amount, valid for one year. Of course it didn't suit me, I was certainly financially damaged. In this case, the financial loss is not the most important thing, it is an ugly way of doing business and fraud by the portal lastminute.com, changing the price of the product at the moment of confirming the transaction, when nothing can be done to stop it. Please avoid the portal lastminute.com, because their way of doing business is ugly, unethical and absolutely unacceptable. I note that I have been buying plane tickets this way regularly, several times a year, for more than 5 years, and I have never felt cheated in such a perfidious way.
