Low-cost airlines Ryanair and Wizz Air were fined by Italy‘s antitrust regulator on Thursday for their hand-luggage restrictions.

The Italian Competition Authority AGCM said extra charges for larger carry-on bags, which the two airlines introduced last year, represented an unfair trade practice.

Being able to take on board a reasonably sized bag as part of the standard airfare is an “essential service” that should not be subject to additional fees, AGCM said.

It fined Ryanair EUR 3 million and Wizz Air EUR 1 million. Both companies were given 60 days to change their luggage policy.
