 The island has three significant airports, Nikos Kazantzakis at Heraklion, the Daskalogiannis airport at Chania and a smaller one in Sitia.The first two serve international routes, acting as the main gateways to the island for travellers.There is a long-standing plan to replace Heraklion airport with a completely new airport at Kastelli, where there is presently an air force base.
