Schiphol ranks high in two rankings of airports in trouble by US news channel CNN. When it comes to most delays this summer, Schiphol is in fourth place. In addition, the Dutch airport is among the top 10 major airports with relatively most cancellations. The listings looked at FlightAware data since the end of May. Since then, 41.5% of flights in Schiphol have been delayed. Only in Paris Charles de Gaulle, Frankfurt and Toronto Pearson International Airport was this percentage higher, according to the list. In fact, more than half of the flights at the last airport were delayed. When it comes to cancellations, Shenzhen Bao’an International Airport in China takes the cake. According to CNN, 7.9 percent of flights there are cancelled. The list includes several airports in China and the United States, one in Indonesia, one in Canada and one in Australia. Schiphol is 10th with a score of 3.9 percent. Due to staff shortages in security and baggage handling, Schiphol has had many problems lately. The airport cannot handle the summer crowds, and therefore has announced measures to reduce crowds somewhat. This is also the reason why airlines have had to cancel many flights this summer.
