I use the duffel for weekend trips that are in the car or camping. But I wouldn't take it on a flight. I use the weekender for plane travel. They did come out with a larger version of the weekender but a friend of mine said it didn't fit under the chair in front of her and had to be placed in the over head bin. When I fly I carry a small carry on luggage and the weekender as my purse. I've never been asked to check it and it fits 2 outfits, 1 pair of shoes, a swimsuit, laptop, makeup bag and a bunch of other junk. I love the weekender.
