I used to travel 2 long haul per month and a couple of short haul per month. This was for about 10 years. I wore out one suit-carrier, and replaced it with one the same.
I bought a cheap wheelie bag in Sin. Replaced this after global research with a "within BA carry-on limits" Samsonite.
Other than the worn out suit-carrier, all the others are still going strong.
...............maybe it's because they never went in the hold.
