Just received this bag and it looks great. Size will be perfect for carry on but because it is so roomy you need to be careful not to pack it over your airlines weight limits.
I just easily packed for a summer trip to Europe using a packing cube and rolling evrything - 3 pants, 3 shorts, 5 T-Shirts, 3 short sleeve tops, 3 vests,  3 long sleeve tops, 2 dresses, 2 skirts, 2 scarves, bathers, underwear, toiletries and 2 pairs of shoes and the compartments are not fully packed, could fit lots more small things in.  The compartment at the back is yet to be packed - plenty of room for documents, ipad, chargers etc.
