At my airline, when you are taller then 2 meter 01 centimeters you have to get a bunch of measurements made. Especially important is the upper leg length. I has to do with the support the seats offer. I live in the country with the tallest people on earth, and we have a lot of guys close to this length. I know of one who is 2 meters 03 centimeters, but his measurements were ok.
Greetings O.
BTW 2 meters 1 centimeters is equivelant to 6 feet 7 inches.
