But long-term restrictions could be devastating
Security restrictions imposed at UK airports have led to an upsurge in airside retail sales at UK airports, but the long-term prospects remain bleak if the new regulations are maintained.

Book retailer Borders said its five airside stores were all very busy. Passengers are not allowed to take any hand luggage through security, but once airside they can purchase goods to take onboard provided they have a receipt to prove they bought the goods after passing through security. Business has slowed at Borders' two landside stores.

All airport staff are subject to the same security restrictions as passengers and may only bring a wallet and keys into work. A Borders spokeswoman said staff morale was high, but 'we are hoping things get back to normal soon, as it is very hard on the staff'.

WHSmith said sales of drinks, magazines and water bottles have risen as dwell times increase and passengers try to find ways to pass the time.

Mintel Research retail analyst Richard Perks said that, if Thursday's ban on hand luggage was introduced on a long-term basis, the effect on the airport retail sector would be huge. 'It would be devastating,' he said.

Evolution retail analyst Nick Bubb said: 'WHSmith remains keen to expand its airport business by picking up contracts from its troubled competitor Alpha Airports and is likely to secure all the shops in Terminal 5 at Heathrow. The airport shops will remain a high-growth part of the business.'

Health and beauty chain Boots is giving away essential items, such as nappies, wipes, baby formula and food, to delayed passengers. The retailer is also keeping stores open 24 hours where it's deemed necessary.
