Equipment when travelling?

I'm starting a new job where I'm giving up car travel for a lot of flying. I'd usually bring one KB with me if I was staying at a sub par hotel, unfortunately I can't bring my trusty KB on a plane.

I don't love bodyweight workouts, I don't know why. I think, mentally, having a piece of equipment puts me in a different headspace, so I was hoping for suggestions on something I can travel with and still get workouts in.

I'm considering getting backpack style rucksack. I have a go ruck plate carrier usually loaded with 45lbs so I'm used to that, but a backpack style I can travel with and possibly use for workouts (if it's loaded heavy enough).

Would appreciate suggestions!
