Budget airline EasyJet has issued a warning that passengers will be stuck on planes thanks to a new rule on EU border checks.
A new scheme known as the EU Entry/Exit System is being introduced in the EU in November.
Under EES, travellers from non-EU countries such as the UK will need to have their fingerprints scanned and a photograph taken to register them on a database when they enter a member state, with the data stored for three years.
There are serious fears this will spark queues at EU airports, as well as the Port of Dover, Eurotunnel’s terminal in Folkestone and London’s St Pancras railway station, where French border checks are carried out before people embark on cross-Channel journeys.
In an interview at the annual convention of travel trade organisation Abta in Costa Navarino, Greece, Mr Lundgren said it is possible EES will cause airport terminals to be congested with arriving passengers waiting to be processed, leaving no room for additional travellers.
“In the worst case you actually can’t disembark, you hold people on the plane,” Mr Lundgren warned.
He said: “We have to think about what can actually happen.”
Mr Lundgren predicted “there will be some disruption” from EES as “it is a new procedure”.
Neil Swanson, who was made UK director for tour operator Tui last month, said there “could be some hiccups” with EES, and urged the Government to take more action to ensure holidaymakers are prepared.
He said: “We will absolutely be looking after our customers, we will be making sure they’re aware.
“But I think the Government should be doing a bit more as well to make sure that everyone’s aware of what the situation is.”
