It's a nice, lightweight bag that fits in the overhead bin on regular jets.  Four stars instead of five due to minimal organization pockets inside.  Has a clever clothing carrier inside the lid.  Comes with a tow strap that has a folding hook to quickly link up the next bag -- it towed two 45-lb checked bags with ease.  Used with Travelon Bag Bungee, Amazon product B001TR0UZI, to carry my laptop backpack through the airport with ease.
