I like that it's red, in case hubby still somehow would have to check this bag.  But supposedly from the title of this product it can fit under the seat, so when hubby has his next business trip we'll find out if that's true!  Why only 3 stars, especially when we haven't officially put it to the test yet?  Well, the workmanship of the particular bag we got is sloppy.  One of the inside pockets is not sewn in exactly straight across, and the bag doesn't puff out nicely such that the label stays straight, rather the label caves in on one side.  Hopefully when the bag is filled up that won't be so much of a problem.  Oh well, I used gift cards to get this, so since I didn't pay full price I can't really complain.
