Way too little baggage drop off counters at Stuttgart airport: over 1:20 in line, with 30 minutes through security had to run through the airport to make it last minute. Others did not make it. Then spent 45 minutes in Amsterdam on the runway for unloading of baggage of passengers who did not make it with the result that they then missed to reload 3 containers of luggage including one of our bags which has still not arrived after 3 days!
