Airline passengers in the UK are being told not to take their own food on flights.
New guidance from the Department for Transport (DfT) says any food items or powders should be "packed into hold baggage where possible", the Daily Mail reports.
Transport officials say that storing food in carry-on bags can obstruct images on the x-ray machine or may be mistaken for suspicious items, leading to additional checks.
But they insist that passengers won't be stopped from travelling with food but those that do should "allow extra time at security."
The new rules will affect the thousands of UK airline passengers who prefer to take their own food when they fly to avoid paying the premiums charged by airport retailers or airlines.
