Carryons(new word?) are getting to be too much in fashion. That's why space is always a problem. I usually fly DL and there seems to always be a delay while some person's second bag has to be gate checked. I only carry a small carryon bag when I am out for a one-nighter. Otherwise I check and have not have any lost bags in past 15 years. Only twice during the period was a bag delayed-then delivered to hotel. A long post for me, but I feel that being hammered by a shoulder bag, having to wait or having something crushed by the inconsiderate should not be part of the ticket price for all travellers.
