It's actually too big and I had a lot of stuff to bring on my trip. Airlines take it on checked baggage without comment. It's well structured , I've sat on it in the vertical position as I waiting in line. The wheels run smooth along the airport floor so it's physically easy to get from terminal to terminal. The only issue is, the wheels are not durrable enough to pull along old cracked sidewalks or for long distances so I've had to take taxi's when normally I would have walked. The suitcases with two big neoprene wheels are better for distance.
