I'm a college student who carry my 15.6'' laptop with me to school often, spending about 50 minutes on the trip. I can't say the airlifting function is a great help, but the bag did keep my laptop and all my other stuff dry. It has more compartments than necessary, but this is just what I prefer. It looks wonderful too. The straps look very sturdy and seem to be able to last for a long time. I'm considering purchasing another one for my younger sister.
