LUTON Airport has refused to apologise for forcing journalist Mary Kenny to strip, saying it was standard procedure.
The writer was left furious after security officers refused to believe that metal detectors were being set off by her hip replacements.
A spokesman said that while it "regrets" that Ms Kenny is unhappy with her treatment, the airport "follows Department for Transport guidance on all security search processes".
"It is a requirement to resolve activations of the archway metal detector in each and every case.
"If this cannot be resolved by a standard search then it is necessary for a private search," the spokesman said.
Ms Kenny, a columnist with the Irish Independent, told how she was about to board a flight from Luton to Kerry on Tuesday when airport security took her into an isolation room.
"I have two hip replacements and I normally just tell airport staff before I go through the security sensor," she said.
"They made me take off my dress, my tights and my knickers and show them the scars. They examined the scars."
The airport spokesman said: "We regret that Ms Kenny feels that she has not received the level of service we endeavour to deliver. To date we have not received any correspondence from Ms Kenny on this matter."
