It seemed I was always doing gymnastics in my airplane coach seat, trying to retrieve something from my under-the-seat bag that I needed during flight.  And if I put the bag in the overhead, it seemed the seatbelt sign would stay on for most of the flight, leaving me without my in-flight items.  This organizer solves everything.  I pack it with the stuff I need during a flight and just carry it like a purse through security and onto the plane.  After the plane is in the air, I bring it out, set it up on the travel tray and all my necessities are within reach.  I reach for this bag FIRST whenever I am packing for travel.  It really is one of my favorite travel items.
