The end of 'free' flights: Airlines told ticket prices must include all taxes, fees and extra charges

The move means airlines must include all airport taxes, fees and charges in the basic ticket price advertised to travellers.

All costs known at the time of publication must be clearly set out, making plain the total price customers will pay.

The new rules had already been agreed by EU transport ministers but needed today's go-ahead from MEPs in Strasbourg.

The aim is to end misleading promotions in which ultra-low air ticket prices are highlighted, leaving out extra unavoidable costs which travellers must pay.

A European Parliament report on transparent air fares said air passengers have as much right as any other consumers to clear and comprehensive information about the price they actually have to pay - including online.

Conservative MEP Timothy Kirkhope commented: "This adds much needed transparency for passengers. It means that website prices and brochure prices will become open and clear. It is the right approach to ensure that price rises are not hidden any longer."

Labour MEP Robert Evans said: "The European Parliament is protecting British citizens. The days when airline advertisements can be a con are over."

Fellow Labour MEP Brian Simpson said holidaymakers would welcome the new clarity, adding: "When you spot a bargain flight online you'll be able to see the real price up front.

"It is time that consumers were clearly informed about the choices they make. When booking a flight online the price they see must be the price they pay."
