I'm biding my time. The days of Self Service kiosks and On-Line Check In are numbered - there will be a major incident arising one day from the airlines' naiivety in believing that (a) a passenger wouldn't dare try to check in someone else (b) a passenger wouldn't dare check in baggage for a flight on which he wasn't going to travel and (c) that iris scanning technology is foolproof (it isn't)!!!
When (and I say when not if) something goes wrong, humankind are going to be recruited by the aviation world as never before!!!
