Punctuality

Next to safety, punctuality is a decisive quality indicator for DFS. Existing routes and procedures are continuously optimised to ensure a high level of punctuality.

In 2017, 5.8 percent of the flights were affected by air traffic flow management measures, for example due to bad weather. Roughly 94 percent of all flights reached their destinations without delay.

DFS defines as "delay-free" those flights which have less than a 15-minute delay under the control of the air navigation services.
