Passengers flying from Dublin Airport are now being charged for resealable plastic bags in which to carry liquids on board.

Dublin Airport Authority has begun charging customers €1 for two bags.

EU measures to combat terrorism introduced in November 2006 restrict air travellers from carrying liquids and gels on board in containers greater than 100ml.

Containers which are permitted on board have to be placed in a clear plastic bag for inspection at security.

Until now, the DAA has been providing these bags free of charge at a cost of €70,000 a year.

Bags will only be available to buy from a vending machine.

The DAA says Dublin is one of the last airports in Europe to introduce such a charge and that passengers can avoid the expense if they plan ahead.
