I have a short scale Jaguar. It is soundwise very P-bass (on the P pickup, that is) so maybe not very different. It is not super light, though, and weight costs if you are travelling by plane. Especially if you travel as your username indicates.
If I were in the situation You describe I would consider a Traveler ultra light bass. I have not tried it myself but from the reviews at Thomann's the sound seems to be their weakest point - if you can live with the ergonomics. If sound is important a preamp/signal conditioner is probably needed - or you can upgrade it with a conventional magnetic pickup.
