Ryanair (RYAAY) said Monday it asked EU authorities to take action to limit the sale of alcohol at airports and provided details about last week's civil case against a disruptive passenger for which it is seeking more than 15,000 euros ($15,320) in damages.

The company outlined the costs and fees it incurred due to the unruly passenger on its flight from Dublin, Ireland to Lanzarote, Spain on April 9. As a result of the disruption, over 160 passengers and six crew members had to divert to Porto, Portugal and stay overnight, then continue to Lanzarote the next day. Ryanair confirmed on Jan. 8 that it filed the civil case against the passenger in Ireland.

Airlines like Ryanair already restrict alcohol on board, especially in disruptive situations. However, during flight delays, passengers can consume excessive alcohol at airports without any restrictions, the company said, adding that "we fail to understand why passengers at airports are not limited to two alcoholic drinks."

Shares of Ryanair were down over 4% in recent trading activity.
