Currently, no airport in the EX-YU region has flights to the United States. However, this summer, both Belgrade and Zagreb are expected to be linked with a 1 weekly service to Chicago. Croatia already has a free sky agreement with the United States while Serbia is also negotiating with US authorities.
Meanwhile, the low cost Austrian airline Niki will commence 2 weekly flights from Vienna to Skopje this September. The airport's management believes Skopje could handle up to 900.000 passengers this year and is negotiating with other high profile companies to commence flights to the Macedonian capital.
