After the ash cloud left thousands of people stranded across Europe in April and May, the European Commission (EC) has launched a publicity campaign on passenger rights.
The Europe-wide campaign in 23 languages aims to inform travellers about the treatment they can expect when travelling by air and rail, covering issues such as cancellations, delays and lost luggage.
Siim Kallas, VP of the EC and responsible for transport, said he wanted to make it "as easy as possible" for people to travel "knowing that they have rights and how to get support in claiming them if they need to".
"There can never be too much information," said Kallas. "We hope that with eye catching posters in airports across Europe, and using leaflets and online information in all EU languages we can reach out to millions of passengers travelling this summer and in the months to come."
In a statement, the EC admitted that although legislation to ensure air and rail passengers get the same standards of treatment throughout the EU has been introduced, not all passengers "are yet aware of what they are entitled to".
Posters reminding passengers of their rights will be displayed in airports and train stations in all EU member states.
A dedicated website has also been launched at: http://ec.europa.eu/passenger-rights
The EC also announced it plans to extend passenger rights to other transport modes, in particular for passengers travelling by sea or inland waterways and by bus or coach.
"Depending on legislative developments at European Parliament and Council, such proposals might be adopted as early as this year," said the EC.
