Carry on clothes
When travelling away from home always take a spare set of clothes as well as toiletry essentials in your carry- on just in case your luggage is lost by the airline. In particular, at night when you arrive at your desintation very late and you would only have what you are wearing and cannot buy any clothes until the next day. The least to take on board is spare underwear,socks, toothbrush, tooth paste, and face cream. It has worked for me a nubmer of times, as sometimes luggage did not arrive until more than a day.
