The European Union announced Thursday it was proposing new regulations to ensure fair competition among all carriers serving Europe.

According to Reuters.com, the proposal would permit an EU member state, airline or association to file complaints to the European Commission regarding alleged discriminatory practices or illegal subsidies, which will open an investigation if there is evidence of a practice causing injury to one or more EU carrier. The proposal needs to be approved by the European Parliament and member states.

“We want to ensure that Europe remains a leader in international aviation, well connected to fast-growing markets, with efficient European skies,” said Violeta Bulc, commissioner, EU Transport.

The decision was made after European airlines Air France and Lufthansa complained the Gulf carriers have been receiving illegal government subsidies. Other complaints have been filed by airlines in the United States as well.

Gulf carriers, including Emirates, Qatar Airways and Etihad, all denied the allegations. The proposal states if the European Commission deems a country or airline is causing injury or threat of injury to European airlines, the group will impose financial penalties or suspend ground and other services. The hope is for the new proposal not to interfere with existing, bilateral air-service agreements.
