Exactly, topsie. I've had the devil of a job with that in airports and stations. Now that 'left luggage' is a thing of the past due to bombs, you have to tote the blasted cases everywhere. I've sat on a loo with a case across my knees before now! Even a cabin bag can be quite bulky in a tiny space. Okay if there's two of you so one can guard the bags, but I always travelled alone - nightmare!
