This suitcase is replacing some very old, very cheap luggage, so I admit my standards were pretty low to begin with.  However, the Avolve 29 is definitely a great piece.  The 4 wheel spinner design is nothing new, but I can see why it has caught on.  Navigating this large piece of luggage was quite easy - getting through narrow lanes with my old luggage required me to pick it up and carry it sideways, as the wheels only went one way.  With the spinner design, I can just stand it up straight and roll it sideways through tight spots.

The suiter supplied is also a nice touch - this is the first piece of luggage I have owned with one.  I always had trouble figuring out how to put my suit in my old luggage in such a way that it wouldn't get squished and creased, but also wouldn't slide around and wind up falling to the bottom of the case.  This completely solved that problem.  It was a little bit of a tight squeeze - I fit one suit and one dress shirt in it and I don't think it would accommodate much more.

I can't speak to the size and airline regulations - people have been commenting about how airlines are getting picky about specific dimensions (vs. total linear size) lately even for checked luggage.  I tend to fly US Air domestic flights and haven't had so much as a second glance from the person checking it.

The durability is probably my favorite part of this luggage.  There is a nice solid feel to it, the fabric is tough and nothing looks or feels like it's going to suffer too much from a little rough handling behind the scenes!  So far, it's survived very well.
