A layover（临时滞留）or flight delay can be extremely fun in these international airports.

Munich Airport, Germany

Aviation（航空）lovers passing through Munich can take a behind-the-scenes tour to learn how the airport operates. Visitors can also tour three historic aircraft and a retired rescue helicopter, climb up to a 28-metre high observation platform for an up-close view of take-offs and landings, and watch films on aviation in the airport’s 60-seat cinema. Travelers can also kill layover time at an 18-hole mini-golf course, or even stop in for a teeth cleaning at the airport dental office.
