First, they pretend they made me save 40 EUR on a ticket (when the reduction was of only 5 EUR) in exchange of subscribing to their Opodo Prime program. I was told this membership, with a free month offered and then 50 EUR a month or so, can be canceled at any moment... But... it seems like a nightmare to get it canceled! No way to cancel it on the website and when you call the customer service - after making you wait for such a long time - they tell you you cannot cancel the membership or it will also cancel the flight you just booked and you have to call back in two weeks...! My experience with them has been terrible - stay away!
