The airline industry has entered a period that has never been experienced before. The retraction in demand due to the COVID-19 coronavirus outbreak, travel restrictions, border closures, corporation travel bans, and economic decline have resulted in airlines being able to offer skeleton services, if at all. On this page you will find information, guidance and resources related to COVID-19, restart and airport slots.



On this video we explain why a slot waiver before the end of July is essential for airlines to plan a realistic schedule for Northern Winter 2020:
