I have this bag. It's an okay cooler, and an okay flight bag, but it doesn't do either task super well in my opinion. The cooler section isn't really large enough if you are a tupperware/meal prep kind of person, but it holds my snacks and leftovers from dinner just fine. Decent storage space otherwise but not for large items. I can barely squeeze my clarity aloft case into the "main storage" section. I was trying to avoid carrying three bags but If I could go back I would probably just buy a smaller briefcase style bag to bring stuff to the flight deck with me, and a separate cooler for food. Also it won't fit under an airplane seat standing up. Sort of annoying when you put it under there laying down and something opens up from being tipped over and leaks everywhere.
