When we went to europe, only one carry on (handbag counted) so folded mine up and put in my rolling duffle. On plane, pulled it but my wallet, etc in it and used it all over europe, held all the things I needed for sightseeing and not worried about my good designer bags.
Bought mine in Helsinki around 2 summers ago, cruise was there for one day and the longchamps store gave us an extra discount. Think the price was 50% cheaper than the prices in the states, my only regret is I did not buy several different colors
