The provision of in-flight first aid equipment and the training of cabin crew to tackle mid-air emergencies will be investigated by the Dáil Transport Committee today.
The move follows the death of a 24-year-old woman on board a flight from Italy last month.
Martin Brady, a member of the Dáil Transport Committee, said the sudden death of the young woman had raised serious concerns about the levels of equipment which airlines are required to carry.
"Passengers have a right to expect proper care if they fall ill or suffer sudden injury on flights. Today's hearings are an important opportunity for the authorities to explain what procedures are in place," Mr Brady said.
"As airlines cut costs, the travelling public needs to be assured that emergency equipment intended to safeguard passengers is not downgraded in the pursuit of profits. Safety is paramount and cannot be sacrificed," the Fianna Fáil TD added.
Mr Brady said he would be seeking assurances all airlines flying into and out of Ireland will have equipment and staff to provide basic first aid from the Irish Aviation Authority and the Transport Department when they appear before the committee.
"Officials will also be asked what procedures are in place to ensure that the equipment is ready for immediate use and that cabin crew are trained to provide first aid which is often vital when people suffer a sudden illness."
