I was always fly light and if I need to wear a suit, I wear it on the plane. It is because of the fear that they will lose my luggage and my vacation/business will be impaired. So on I go with my laptop and my backpack that carries my deodorant, tooth brush, socks, one pair of jeans, undershirts and boxer shorts. Never can have too little of those.
But The Economist has polled to find out which European airlines are most prone to lose luggage.
I'll still continue to do it my way. Saves a lot of time just going to the car rental and not have to queue in front of the baggage claim.
