Depends on the airline ;-) You will need to measure your pack and compare that measurement with the 'allowed hand luggage measurements' of the airline you are planning to use.

Hi, looks good, below some thoughts:
BackPack
Deuter Futura Pro 40 (Rain Cover)
OR
Osprey Talon 44 (no rain-cover) Which ever fits better fully loaded.
Hydration
Hydration pack for chosen backpack (Preferred) or 2 x 500ml...
If you are on a longer Camino, and especially in warm or hot weather, you should clean your water bladder regularly. I always wonder how many stories of 'bad tummy bug due to bad water" actually should be called "bad tummy bug due to rarely cleaned water bladder" ...

I think it would work better the other way round: Post what you plan to take and we all can give you feedback ;-)
The big two are: The backpack itself (empty weight does differ from model to model) and your sleeping bag, then clothing including rain gear and so on ...

I have used both, I find a frameless backpack perfectly comfortable as long as the total load is less then 6kg (including all, water and food) more than that I prefer a backpack with a frame.
