The committee would prepare a cadre-wise single and unified provisional seniority within 15 days and seek objections from any employee, an official statement said.
Civil Aviation Minister Ajit Singh was quoted as saying that the final list of cadre-wise seniority be finalised within next 45 days.
The AAI had come into being after the merger of the erstwhile National Airports Authority and International Airports Authority.
The statement said that the final seniority list will be published in another 15 days after disposing off the objections received thereon.
