WORST airline ever. I flew from MAD to Marrakech with an ADDITIONAL PAID carry-on which perfectly passed. At the return, I used the same bag (which I ALSO paid) did not pass (for 1 CM, half of the bad wheels). The desk lady was disrespectful and wanted to cheat on us on propuse. This is not a low cost airline, this is a trash company that scams, lies and STEAL their customers. Never, NEVER, again.
