IRELAND:There was relatively little disruption reported at Irish airports yesterday, when schedules began to return to normal.
Two Aer Lingus return flights between Dublin and London Heathrow were cancelled at the request of British authorities, while two Ryanair flights from London Stansted - the first to Dublin and the other to Shannon - were also cancelled.
A spokeswoman for the Dublin Airport Authority said "business as usual" had resumed.
The latest restrictions on hand baggage are: when travelling from Dublin/Cork/Shannon airports to Britain, there is no change to hand baggage security policies. One piece of hand baggage is permitted while restrictions on hand baggage when travelling from British airports have eased. Passengers can now take one piece of hand luggage on to planes but are still banned from taking liquids aboard.
New guidelines issued yesterday stipulate that a passenger's single item of hand baggage may be no bigger than the size of a laptop or a small rucksack: 35cm (13.5in) wide x 45cm (17.5in) long x 16cm (6.5in) deep.
The bag must not contain any liquids, cosmetics or toiletries (including gels, pastes, lotions, liquid/solid mixtures, perfumes and the contents of pressurised containers).
Cigarette lighters are not permitted in hold baggage or through the security search.
The bag can include electronic equipment including mobile phones, digital cameras and mp3 players, as well as prescription medicines in liquid form.
Baby milk and liquid baby food are allowed, but the contents of each bottle must be tasted by the accompanying passenger.
Laptops are permitted, although they must be removed from their case for X-ray.
All remaining items in passengers' pockets (eg, keys, cash, books, newspapers, cigarettes) should be placed in the clear plastic bag provided. Once in the departure lounge, passengers are free to buy any item and take it on to the aircraft as normal.
The US Department of Homeland Security yesterday issued new security instructions for passengers travelling to and from the US.
As a result, passengers are not permitted to carry liquids or gels through the screening checkpoint. There is also a ban on bringing liquids bought inside the security area on board.
On Sunday a British Airways flight to New York turned back to Heathrow because of a security scare over a ringing mobile phone that did not belong to any of the 217 passengers. The phone was later found to be safe.
Mobile phones were banned from hand luggage as part of the stringent security measures rushed in last Thursday after police arrested 24 people suspected of involvement in the alleged plot to blow up as many as 10 airliners.
