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.
Changi Airport, Singapore
After a long flight to Singapore, travelers can relax in a Balinese-style swimming pool, work out at the airport gym, or enjoy a drink and live musical performances at the airport's Music Bar. The airport also has a quiet butterfly garden, and a "pleasant-smelling garden" which is home to 15 species of plants and trees. Free movies at one of two airport cinemas also keep passengers entertained.
Schiphol Amsterdam Airport, the Netherlands
Schiphol is Europe's fifth-largest airport. Here passengers can view the works of Dutch masters free of charge. You can even have your wedding ceremony at Schiphol — couples can choose from four different wedding packages, including a 1930-style ceremony held on a Dakota military aircraft.
San Francisco International Airport, California
The airport's 24-hour AirTrain not only moves passengers between terminal, but also provides a fun view of the runways. There are three aquariums (水族馆) to explore, along with interactive play areas, an aviation museum, and a library. If that's not enough to keep the little ones busy, travelers can rent portable DVD players and movies for use in the airport.
