Nationwide baggage-scale inspections
The baggage scales used by airlines are being inspected regularly for accuracy.
Overweight checked-in bags are often accompanied by hefty airline fees, which can result in an unwelcome and unexpected addition to the holiday spend.
The State measurement body, the National Standards Authority of Ireland (NSAI), inspected 346 airline baggage scales this year and none were found to be inaccurate.
Using a set of calibrated weights, inspectors from the NSAI found that the weigh scales were on the mark at Dublin, Cork and Shannon airports.
"We carry out these regular inspections to give people the confidence that the weight displayed by the airport weighing scales is correct," said Paul Turner, NSAI's head of legal metrology.
"It also means that if excess charges are added based on a particular weight, people can be sure that they have been applied fairly."
