The call comes as the airline sues a passenger for €15,000 after they caused a flight to be diverted.
From Euronews, Ryanair is demanding that passengers be stopped from drinking too much before boarding flights.
The budget airline believes it would help with the growing problem of disruptive behaviour onboard its flights.
“It is time that EU authorities take action to limit the sale of alcohol at airports,” the Irish airline said in a statement.
"We fail to understand why passengers at airports are not limited to two alcoholic drinks (using their boarding pass in exactly the same way they limit duty-free sales), as this would result in safer and better passenger behaviour on board aircraft, and a safer travel experience for passengers and crews all over Europe.”
