I'm having a very hard time finding a replacement for my carryon that has now broken twice and I can't fix again (i've had it for 15 plus years). I'm trying to find something that is 20.5 to 21 inches long counting the wheels - which is what my old carryon is. I want soft-sided luggage. I've been searching for days and cannot find anything anywhere. I'm finding plenty that are 22-23, but I've used 22 before and it's too big for some planes imo. I'm also finding 18 inches (including the wheels) but that's too small for my needs. I also need spinner wheels.

Are there any places or even brands that would have this particular size? I think I found 1 suitcase that fits my criteria, but it's almost $500 so I want to avoid that if I can.

I've looked:
Kohls
Macys
JcPenny
Google Shopping
Target
Walmart
Costco
Sam's Club
Bed Bath Beyond
American Tourister
LL Bean
Luggage Pros
Samsonite (which is the brand of my broken carryon)
Amazon (is full of fakes so I tend to stay away from them)
