NEW DELHI: Air India on Tuesday issued a travel advisory asking passengers to check their flight status before heading to the airport, as a third-party system disruption affected check-in operations at multiple airports and caused delays across several airlines.In a post on X, Air India said, “A third-party system disruption has been affecting check-in systems at various airports, resulting in delays across multiple airlines, including Air India. Our airport teams are working diligently to ensure a smooth check-in experience for all passengers. While the system is progressively getting restored, some of our flights may continue to experience delays until the situation fully normalises.“The airline urged passengers to verify their flight status through its official portal before starting their journey. “We request passengers to check their flight status at “https://airindia.com/in/en/manage/flight-status.html” before leaving for the airport, and to allow additional time for their journey. We sincerely appreciate your patience and understanding,” the airline added.Airlines worldwide occasionally rely on third-party service providers for check-in and operational systems, and disruptions of this nature can lead to cascading delays. Air India said its teams are working to restore services and minimise inconvenience to travellers.
