It comes as misbehaving passengers have caused flight delays impacting others.
Ryanair has announced it's now taking legal action against disruptive passengers.
The airline has filed a claim for over €15,000 in damages against a passenger who disrupted a flight from Dublin to Lanzarote last April, forcing it to redirect to Porto. 
In a statement, the company owned by Michael O'Leary says it's completely unacceptable for hard working people to have a trip ruined by "one passenger’s failure to behave". 
Business Editor Joe Lynam says this could set a precedent for other airlines to take similar steps:
