Ryanair's criticised a Spanish court ruling over its baggage policy.
It's after a woman was charged €20 on a flight from Madrid to Brussels.
The passenger had a bag weighing 10 kilograms and didn't have a 'Priority' ticket.
The Provincial Court of Madrid said it considered the charge "abusive".
It said it "condemns" the company for forcing the passenger to pay at the time of boarding - even though the carry-on bag, by its size and weight, "could be perfectly transported in the cabin".

The court also ordered Ryanair to return the €20 fee to the passenger plus interest.
It's ordered Ryanair to remove the clause from its terms and conditions.
In response, Ryanair said: "This ruling will not affect Ryanair's baggage policy.
"It is an isolated case which misquoted the [Court of Justice of the European Union] and misinterpreted the airlines' commercial freedom to determine the size of their cabin baggage".
