Doesnt work that well for airline use, needs few things. It fits but......
Reviewed in the United States on December 23, 2018
Used this for the first time on a Jet Blue flt on Dec 22 2018. Its does fit easily under the seats (aisle, middle, window) on a A321 aircraft. Rolls easily but the rear strap that's supposed to fit over the handle on wheeled luggage in no way will stretch any amount to pull it over the telescope handle. No slack at all to do this. And there is no side handle to hold the bag while trying to do so. So you are wrestling and trying to fit this bag over the telescope handles with both your hands while the bag is sideways. and I was unsuccessful in doing this. For these two reasons I will be returning the bag.
If used as an airline underseat bag its size works well. With today's reduced seat pitch this bag is somewhat difficult to pull out from underneath the seat when seated . So get your things you want in flight before you settle in for the flight.
If using this bag for non airline travel this bag may be great for the commuter, office, school function as it is small and rolls easily.
Guess I'll keep looking. I travel about 25-30 airline flights a year
