This is a great luggage set. I've taken it on one Delta trip. The larger bag fit perfectly in the overhead bin and the small bag fit under the seat with room to spare. The extra space afforded by the recessed wheels was very helpful. I was able to fit enough winter clothing and toiletries for a week. This included make-up, hair stuff, and a couple of heavy sweaters. My family was shocked that I only needed the two pieces plus a small crossbody purse.
