I purchased one Eagle Creek 22" Tarmac and one Samsonite 22" spinners because I wanted two of the Samsonite's, but my local Bed, Bath and Beyond only had one in stock.  The Samsonite four wheeled function 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.  The Eagle Creek worked fine as a traditional pull bag.  No complaints.

This is my third 22" carry on and all of them have trouble fitting in the overhead bins no matter which airline I fly.  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 did fit better than the Samsonite which 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 the Samsonite would have passed, however, this one might have as long as you don't use the expanding feature or put much in the outer pockets.

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.
