For those who may be like me and were looking for the largest bag they can get away with in the overhead of a CRJ700 or CRJ900, this bag fits just fine.  I packed it completely full and had no trouble fitting it into the overhead.

Even if overfull, it would probably work as long as its full of clothes or something that will can compress so you can cram it in there.

Bag held up fine on our trip, although it stayed mostly in the hotel so use was minimal.

The little pocket on top which I did not expect to use was excellent for carrying keys and phone when going through security.

Very satisfied with this bag.  I wore
t-shirts and shorts for the entirety of our trip and was able to fit everything in this one bag for a 6 night trip.
