I purchased one of these bags and one Eagle Creek carry on 22" because my local Bed, Bath and Beyond didn't have two in stock.  It wheeled great in the store, however, once at MIA it was okay.  If the floor is not very even or is carpeted I had to pull it the traditional way.

I love the red color and overall like the suitcase, but the biggest problem with ALL the 22" carry ons is fitting in the overhead bin.  I do NOT use the outer pockets nor use the expanding function, and on American Airlines it would not fit it handle out/wheels in.  A man helped me and turned it around and it barely fit after a few good shoves.

I decided to check this bag at SJU airport, and unlike MIA they actually took the time to weigh the checked bags.  Just prior to entering the plane they pulled aside people with bulky or questionably sized bags and put them into a bag checker.  A woman in front of me didn't pass.  I don't think this would have.

After trying three different brands of soft sided 22" carry ons I think I'm going to switch to a smaller bag probably hard sided and do what I saw other people doing.  Use a backpack or similar bag for my "personal item" and store a purse.
