Scores of Air India passengers were stranded at several airports across the country as a technical glitch in the airline’s check-in software delayed 25 flights on Saturday, officials said.

Union Minister of State for Civil Aviation Jayant Sinha tendered apologies for the inconvenience caused to the passengers.

Services remained affected for three hours from 12.10 pm to 3.10 pm, the airline said, as passenger queues kept swelling at check-in counters.

Some unconfirmed reports suggested that some international services were also affected at the IGI Airport.

Air India’s software solution is managed by SITA, a global airlines IT services solution major, which provides its check-in, boarding and baggage tracking technology.
