I use my Air Boss almost exclusively for weekly business travel. I nearly always pack one (and sometimes two) suits in it. If I use the bundling method from onebag.com, my suits / dress shirts / ties come out less wrinkled than any other method I've found, including roll aboard suitor, garment bags, dry cleaner bags, rolling, or even wearing it on the plane.

For me, it hold three days worth of business travel before it gets over 20 pounds (one suit, blazer, jeans, 2-3 shirts, change of shoes, toiletries, socks / undershirts / underwear). If I need to pack more than that, I use my Briggs roll aboard, but that requires me to gate check on RJ travel.
