I was kind of sorry I bought this because once I got it all filled, I could see it was way too much bag for me to handle with just two wheels and I had a very hard time maneuvering it around the airports.  Don't get me wrong, its very well built and you can fill it nicely as it holds a lot of stuff.  It held up fine in transport, etc. but it didn't balance all that well when full and I could see after one use that what I should have done was spring a bit more $ and get one with 4 wheels, because even though it's the kind you have to check, you still have quite a ways to haul it, both to the ticket counter from your shuttle/parking/etc, and at the other end at baggage claim. If you are a strong person, this may be the bag for you, but if you are an older woman like me, you may want to get something else with 4 wheels.
