I would put 0 star but I can't. Scam and rubbery, that are the 2 most convenient adjectives I can use. Short story, I booked a ticket via Opodo with British Airways. There was a clear message saying that I can add a baggage after the booking without any condition. The day before I've tried to add baggage but I'm unable to do it. I've spent 4 hours with the customer service on the phone and all they could confirm is that "They are sorry for giving a wrong information and they can do nothing for me" and "I can add baggage in the airport" without giving any guarantee that I can do it, and without details on the cost price. Knowing that I have 60kg baggage, I don't want to take a risk and go blindly to the airport. As a result, I'll need to book another ticket, take 1 or 2 more nights in the hotel in London, and I don't talk about the waste of time and energy, stress and other prejudice. Anyway I've recorded the conversation, I'll take Opodo to court
