BRITS buying tickets now for flights that leave after Brexit can’t be guaranteed that the plane will take off.

UK airlines are preparing messages for their websites that warn customers about the risk of buying tickets for after March 2019.

The notices would start to appear around spring 2018 if the government has failed to break the deadlock in Brexit talks with the EU.

It would affect tickets to EU destinations as well as up to 17 other countries, including the US, because flights to places like America are covered under current EU regulation.

If the flights are grounded as a result of no deal being struck after Brexit, then airlines would compensate passengers for the cost of their flights.

But any extra costs usually covered by airlines based on EU regulations – like compensation – would not be paid out.

At the moment, air traffic in the EU is governed by the Single European Sky arrangement that allows planes to fly without restriction from one European country to another.

That will have to be replaced with a new treaty when we quit the bloc to enable flights to continue as before.

Earlier this month, Chancellor Philip Hammond warned MPs that all air traffic could “theoretically” stop the day after Brexit.

Quizzed by the Treasury Select Committee today, the Chancellor mentioned air travel as one industry which could be affected if we leave the EU without a deal.

He said: “It is theoretically conceivable that in a no-deal scenario there will be no air traffic moving between the UK and European Union on March 29, 2019 - but I don’t think anyone seriously believes that is where we’ll get to.

“So there are a range of outcomes. What we will need to do at a point in time is determine what a realistic worst case scenario that we need to plan for and invest for.”

According to The Times, airlines are optimistic that a deal will be struck between Britain and the EU.

But there is some concern that the government won’t approve an aviation deal if it has to abide by certain European Courts of Justice rulings.
