Strict security measures have been brought in for air passengers flying from the UK after a suspected plot to blow up planes was prevented.
The arrangements, announced by the Department for Transport, apply to all passengers starting their journey at a UK airport, and to those transferring between flights at a British airport.
All cabin baggage must be processed as hold baggage and carried in the hold of passenger aircraft departing UK airports.
Passengers may take through the airport security search area, in a single, transparent plastic carrier bag, only the following items. Nothing may be carried in pockets:
Pocket-size wallets and pocket-size purses plus contents (for example money, credit cards, identity cards, etc - not handbags)
Travel documents essential for the journey (for example passports and tickets)
Prescription medicines and medical items sufficient and essential for the flight (eg, diabetic kit), except in liquid form unless verified as authentic. Passengers are advised to bring medicines in containers where the seal has not been broken
Spectacles and sunglasses, without cases
Contact lens holders, without bottles of solution
For those travelling with an infant: baby food, milk (the contents of each bottle must be tasted by the accompanying passenger) and sanitary items sufficient and essential for the flight (nappies, wipes, creams and nappy disposal bags)
Female sanitary items sufficient and essential for the flight, if unboxed (eg tampons, pads, towels and wipes)
Tissues (unboxed) and/or handkerchiefs
Keys (but no electrical key fobs).
All passengers must be hand searched, and their footwear and all the items they are carrying must be X-ray screened.
Pushchairs and walking aids must be X-ray screened, and only airport-provided wheelchairs may pass through the screening point.
Any purchases made in departure lounges will be permitted onboard aircraft, with the exception of those flying to the US.
Those travelling to the US will be able to purchase goods for consumption in the airport but no additional items, other than those on the list, can be carried onto the aircraft.
In addition to the above, all passengers boarding flights to the US and all the items they are carrying must be subjected to secondary search at the boarding gate.
Any liquids discovered will be removed from the passenger.
There are no changes to current hold baggage security measures.
Passengers are being asked to allow themselves plenty of extra time and to ensure that other than the few permitted items listed above, all their belongings are placed in their hold baggage and checked in.
If passengers have any questions on their travel arrangements or security in place at airports they should contact their airline or carrier.
