I use Black Diamond.
https://www.blackdiamondequipment.comI do not find my model on the site.
I use the same for a city trip and hiking, mountaineering, etc.
Also perfect for crazy flying, as besides the big volume, it also "sticks" to your body, and so heavier weight is carried effortless, and you can as close to running as possible, in comparison with other backpacks.
For longer and family trips I use a regular trolley.
