A few years back, Travelpro split its luggage lines into two series:  The "CrewX" series is designed to be pretty and marketed to consumers, while the "FlightCrewX" is designed to be rugged and is marketed directly to pilots and crew.  The "Crew8" series is the current version marketed to consumers and the "FlightCrew4" is the current version that is marketed to pilots and crew.

I bought this bag before I came to this realization, and have been disappointed ever since.  I hate the design of this bag.  While it is light, it is much too flimsy to any kind of heavy duty use.  Travelpro included a relatively cheap, but pretty design on the attachment strap and the short handle, both of which are sure to break with significant use.  They've also rotated the axis of the long handle so as to make it harder to slide an extra bag over them.  The front pockets are designed for appearance instead of utility, and so the zippers have a funny looking "U" shape and the pockets actually overlap, while being too thin to really hold anything.  The nylon is a thin weave designed to have a nice "shine" instead of being resistant to damage.

I later purchased a Travelpro FlightCrew4 22" bag from an online store that caters to pilots and flight crew.  What a bag!  Nice sturdy ABS frame, real inline skating wheels, heavy duty handles with the axis in the correct direction, well-laid out pockets, and heavy duty nylon -- and $40 cheaper!  The only problem is that it is a bit larger than Travelpro claims.  So, now I use the 20" instead.

I also own a Kirkland 22" suiter (available only at Costco), which is better than this one and only $99.00.

So, do yourself a favor:  Skip anything in the Crew8 series (or any of Travelpro's consumer lines) and buy the FlightCrew4 from an online retailer or get the 22" Kirkland at Costco.
