I use a 5.11 Rush 12 Tactical Backpack Sandstone as my "personal" item.
The main compartment of the Rush 24 is 20" H x 12.5" L x 8" D, so you might be able to get away with the Rush 24 as a carry on if you don't over pack the exterior compartments.
It has the additional advantage that my Chinese employees thought I was a special forces alumni.
