I'm just back from a trip to Spain. On the way out I took my electric scooter as usual. As ever I kept it till the gate. This time they loaded me using an ambulift, so I was still in my scooter right to the door of the plane and just walked the last few yards. They then take my scooter off the ambulift and put it in the hold (all of 20 yards). In spain they take scooter back out of the hold, put it in the Spanish ambulift and collect me. During this time either one of the assistance people or the baggage handler stole, and yes I mean stole the claiming karabiner that holds my walking stick on my scooter. If they can be that blatant in their thievery, God only knows what they get up to when they are left alone in their baggage handling areas? OK it's no big deal, but it was a pain while I was away and cost me £40 for the replacement.
