Key reasons

Potential causes having an impact on flight planning/ airline choices: 

  • Geopolitical (Ukraine, Libya and Syria);
  • Regulations due to capacity/ staffing problems in the network;
  • Traffic composition/ demand;
  • Industrial action;
  • Weather (several key ANSPs were affected by traffic re-routing);
  • Financial (fluctuation of route charges over Europe).
