( CNN ) -- Need to get somewhere on time ? Do n't book a connecting flight through China . According to FlightStats , a U.S.-based air travel information service , mainland China airports are the world 's worst when it comes to on-time departures and arrivals . Worse still , according to the report , which covers airport and airline activity in the month of June , the overall performance of Chinese airports has become worse in the past half year . At the bottom of the list of major world airports is Beijing Capital International Airport . In June , just 18.3 % of flights from the airport left on time . Around 42 % of flights from Beijing suffered delays of 45 minutes or longer . Second worst on the list is Shanghai Hongqiao International Airport . Just 24 % of its June flights departed on time , compared with a 38.9 % on-time departure rate six months ago . `` None of China 's provincial airports surveyed by FlightStats -- including Guangzhou , Kunming , Nanjing , Chengdu , Changsha and Urumqi -- could manage to get half of their flights on time , '' according to a story in the South China Morning Post . Osaka Airport ( 95.88 % ) and Tokyo 's Haneda Airport ( 95 % ) led Asian airports for on-time performance .

Top performing large European airports were in Amsterdam ( 83.52 % ) , Munich ( 83.35 % ) and Vienna ( 82.15 % ) . China 's major airlines also fared poorly compared with regional and global counterparts . `` Major international airlines on average delivered 75.85 % of their flights to the arrival gate within 15 minutes of schedule in June , down from May 's 80.70 % , '' according to the FlightStats report summary . Map : The best and worst for airport delays . `` Six major international carriers , South African , Gulf Air , ANA , Japan Airlines , Finnair , and Tyrolean Airways , delivered over 90 % of their flights on time .

Top overall Asian performers were Air Busan ( 96.77 % ) and J-Air ( 95.64 % ) . According to the South China Morning Post , the poor performance of Chinese airports and airlines is blamed on `` excessive military control of airspace and poor urban planning . '' `` Nearly 80 % of China 's airspace has been reserved for military use . In other countries , such as the U.S. , the situation is exactly the opposite , '' according to a Hainan Airlines official quoted by the SCMP . To get the full FlightStats report click here .
