Take a look at the Pro Trekker 450 AW, the 650 may be too large for a carry on. I use this pack for mountain trail day hikes. There is enough room for my camera gear and hiking gear. I sometimes go in up to 7 miles and I am safety conscious, so I always include the ten essentials, first aid kit, extra shirt, light shell windbreaker, extra water, extra food etc. I tried to replace the Pro Trekker with the ProTactic 450, but the ProTactic is VERY firm, too stiff. The main compartment lid was not flexible. I couldn't zip it closed with the gear I needed. I returned it and got the ProTactic 350 for use when not in the mountains. I recommend these LowePro products highly. If you can, try before you buy.

The problem is that without any local camera stores anymore, trying before you buy is a thing if the past. :-/
