An airport is a bad place to scooter around. Too many people. That's a big problem. And yes, the weight is another.
Personally, the scooter is way too small. Most scooters actually suck if you are 6'3" and 230lbs (why do you think I do not fly in normal economy for more than a few hours

). Look at the SwiftyONE TALL and you will see the difference.
