Not Verified | My family and I traveled this summer from Austin to Miami, two cities in Colombia, Madrid, France, and New York. We used multiple airlines and took carry-on bags on all of them. We are a family of four, and each of us took a carry-on suitcase. The bags qualified for carrying on in all of the airlines that we used, except for this one. Ridiculous enough, the trip that we used XL airways was an international trip from Paris to New York. At the airport, XL airways had a small compartment to measure the bags that they said the bag needed to fit in, including the wheels. It seems like they were doing this scam often enough because when we were boarding there were three guys ready to take "the bags that people couldn't take as carry-ons" in the plane. The representative told us that it was going to be $100 euros per bag and they took our passports and put us aside with many other people who were going through the same thing we were going through. They pretty much kept us until everyone boarded and told us that if we were going to take the flight, we needed to pay 65 euros per bag and he acted like he was doing us a favor. This was our flight to come home from a long trip, it was really late at night, and we had our six and nine year old exhausted kids with us, so we didn't see any other option than to pay them for the four bags. This is what they have on their website to pay for checked in bags. Also, during boarding time I have never seen an airline as disorganized as this one. There were no lines and they just called everyone at once. Inside the plane, there was no entertainment and the plane inside was very uncomfortable for a trans-atlantic trip. The only bright spot was that the crew was really nice to us, and they served one hot meal during the flight. Do not fly with this airline, they are not worth it, and if it is a family trip, even worse. Here are the measurements that most airlines advertise as carry on: 22 x 14 x 9 in And here is theirs: 21.7 in high X 13.8 in wide X 9.8 in deep. They are not really that much different. We had measured them before we left for the airport, as well as had carried them on several flights previously. I think what they do with the carry-ons is a scam, I will not recommend this airline to any of my colleagues, family or friends who travel quite often. I will not fly with them again!
