I put mine into a large hold all, saves all the faffing about with cling film, etc.
Airlines seem to like it to, no straps to get caught in conveyers, bits falling off, less likely for 'sac to get ripped.
Mine fits into a 2lt sack, weighs 0.75kg, if I'm going back to same airport, I'll leave in left luggage, or as at Information desk if someone can keep for me. I've not had a problem, either way, sometimes one of the car hire desks have kept for me, even if I haven't hired a car.
