Everything I expected.  Thrilled every time the flight attendants want to hand me a ticket for on-board check.  I know it fits under my seat - WITH ONE EXCEPTION - no wheeled bag fits under the seat in the left row on a small commuters configured as 1 aisle 2.  In that case, in recent flight while I was seated on the two-seat side (right of plane), I could not fit this bag in the overhead compartment, but easily fit under my seat.  So, I put my smaller companion bag up top.  As long as you don't sit on the single seat to the left in the 1-2 configuration on those small planes, you are good to go with this bag.  Worst case, go for the boarding check and they'll hand it back when you disembark.  Cheers
