Wow! I actually just combined two things into one - totally awesome! I'm so proud of myself. And I'm within airline measurements. I started out with a small carry on packed to the gills and my computer bag - also packed to the gills. Told my husband, hey check this out and plopped one over each shoulder and thought I was gonna die. After a fast trip to Wally World, we picked out a carry on with wheels - Wha La! everything fit into one and my shoulders are happy campers. Now I can give my son in law back his computer bag.
