New cabin bag rules come into force today at some airports across the UK.

Passengers will be able to carry two bags on board flights at Heathrow, Stansted, Manchester, Glasgow, Aberdeen, Edinburgh and Newcastle.

However, only one piece of hand luggage will be allowed at other airports including Liverpool, Luton, Gatwick and Bournemouth.

Passengers flying with Virgin Atlantic or British Airways are allowed to take two pieces of carry-on luggage, unless they are flying from an airport where the restrictions are still in place. Those flying upper class on Virgin will be allowed two pieces of cabin baggage plus another small handbag, pocketbook or purse.

However, Easyjet, Ryanair and Lufthansa are maintaining the ban on second cabin bags. Easyjet argues the relaxation of the ban will confuse customers.

Restrictions on carrying liquids remain in force at all airports.

The rule was imposed after after an alleged terrorist plot to down transatlantic airlines was foiled in August 2006.

Airports which have lifted the one bag rule: Aberdeen, Benbecula, Birmingham, Cambridge, Cardiff, Edinburgh, Glasgow, Heathrow, Inverness, Islay, Kirkwall, London City, Manchester, Newcastle, Plymouth, Prestwick, Southampton, Southend, Stansted, Stornoway, Sumburgh, Wick.

Airports which still have the one bag rule:  Bristol, Bournemouth, Durham Tees Valley Airport, Gatwick, Leeds-Bradford, Luton, Norwich, Nottingham East Midlands, Liverpool, Coventry, Exeter.
