Network Operations Report – December 2017

16 January 2018

Traffic in December 2017 increased by 1.9% compared to December 2016, a slowdown in growth due to high traffic levels in December 2016 and also explained by recent airline failures. Traffic has shown continuous growth since November 2015. Five states each added daily more than 50 flights to the network with Spain, Turkey and Poland as the top contributors.
