Cabin baggage restrictions will be lifted at Heathrow Airport. Passengers will be allowed to carry more than one piece of hand luggage through security checkpoints from January 7.
BAA has overhauled the security regime at Heathrow by acquiring a new generation of x-ray machines, which can detect explosives and liquids.
British Airways has claimed that the one-bag rule contributed to its baggage problems over the summer by overloading Heathrow's handling systems for checked-in bags. The one-bag limit and restrictions on carrying liquids have been in place since August 2006, when an alleged plot to bomb transatlantic flights at Heathrow was disrupted.
New Year strike threat
AIR passengers are facing New Year misery at Heathrow after talks to avert a series of strikes ended without agreement.
Leaders of the union Unite met for several hours with the airports' owner BAA last week to try to resolve a row over pensions but the dispute remains deadlocked.
No further dates have been set for negotiations although union officials stressed there is still time for another attempt to head off two 24-hour and one 48-hour strike in January.
