I flew Frontier but found the bag did not fit all the way into the Frontier sizer as wheels were too wide. However, I carried it in, rather than wheel it in, and made it through check in. Bottom portion of bag did not fit all way under seat. Nice bag with many pockets

It is a great piece; took it to FL and it fit nicely under the seat; HOWEVER, it’s not going to last a “lifetime” like a better brand; it’s just for the moment…

So this product is great for putting under the seat in front of you on regional planes so you don't have to wait in the gate bridge. I can easily do 2 nights and sometimes 3 with efficient packing. I have had quite a bit of problems with the handle going back in properly and now I can't extend it all the way which is basically making it useless.

I’ve only used it once so far but overall it was worth it. It’s pretty small but nice for a short trip

Does the job as a small roller bag. Would be nice if the zippers were higher quality (larger teeth), but so far they have not broken.

It's Heavy and the telescopic handle is flimsy and wobbles

It is good but the bottom part stands that are black gets scratched up easily. Otherwise nice bag carry on. I like

Ok bag but didnt fit under the aisle seat on my Delta flights
