Hundreds of litres of fruit juice, sun cream, insect repellent and even curries are still being confiscated from Leeds-Bradford Airport passengers two years after security restrictions on hand luggage were brought in.

As thousands of holidaymakers flock abroad this summer, the airport is pleading for passengers to keep to the limits for liquids following an alleged plot to blow up transatlantic passenger jets in August 2006.

Airport staff said they still have to collect the excess liquids, including aerosols, despite the introduction of an awareness campaign, permanent signs near security and passengers being asked if they have obeyed the rules for hand luggage.

“It is a lot more than you would imagine,” said Neil Byrom, a manager for G4S, which deals with security at Leeds-Bradford.

“It is bottles of juice, water, sun creams – anything that people want to take on holiday. We do get other things like curry and sauce that get posted in plastic bins.”

Liquids, gels and aerosols are only allowed in individual containers of 100ml in cabin baggage. All containers must fit “comfortably in one, transparent, re-sealable bag no larger than 20cm by 20cm”, according to the Department for Transport (DfT) site.

Leeds-Bradford Airport does not collect figures on what or how much has been confiscated. But a spokesman said that some passengers were still exceeding limits because they had “forgotten” the ban is still in place or believed it had been lifted.

Sam Wynzar, communications officer at the airport, said a “high level” of liquids was being taken into the security area.

Miss Wynzar said: “G4S, which deals with security, said this is mainly from those that are taking their annual holiday rather than frequent fliers who are well informed about the restrictions. The main problem is the size of bottles as people are not always aware how big 100ml is, so there is confusion over larger containers being taken through of deodorant for example.

“Those who maybe only go on holiday once a year have either forgotten about this or think the rules have changed, but that is not the case. We have a lot of information on our website under the ‘Passenger Information’ section about preparing for your holiday, preparing for flying and checking your luggage, which will be able to answer people’s questions.”

Security staff at other British airports have also reported items in hand luggage including jars of Marmite and marmalade, Moet and Chandon champagne, cans of baked beans and snowglobes.

British Airports Authority (BAA) said passengers were still exceeding the limits at Heathrow.
