Ryanair, Europe’s biggest airline, is going after unruly passengers on its flights and has filed for €15,000 ($15,400) in damages from a passenger who disrupted a flight last year.

Ryanair has launched a £12,500 legal claim against a passenger whom the airline alleges disrupted a flight to the Canary Islands last year.
