This is my favorite carry on suitcase. It holds a ton (at least 5 days worth of clothes) and it's expandable. I love the mesh divider that makes two compartments and that it has the tie down straps. All 4 wheels spin and the handle locks so it's easy to get through TSA check and to your gate on time. It's a pretty Forrest green that stands out from the endless sea of black carry ons. I've used it on Delta, Allegiant, Jet Blue and American Airlines flights and it was within the size permitted.
