Bengaluru: Thousands of passengers all set to travel with IndiGo Airlines on Monday were left stranded across the country. The incident took place after the airline’s passenger system server -- Navitaire -- was down for nearly 30 minutes in the morning due to technical issues.

Passengers in Bengaluru, Chennai, Mumbai, Pune and Hyderabad were the worst affected. They were left waiting in long queues near the IndiGo departure counters for nearly an hour before the check-in process began.

According to reports, the airline’s server was down between 4.29 am and 5.07 am. During this time, manual boarding passes were being issued to the passengers at Kempegowda International Airport. The IndiGo officials reportedly confirmed that the system is now up and functioning normally.

However, passengers immediately took to social media to complain about the server glitch and how they were made to wait for nearly an hour.

A passenger, Amit Baby Oomen tweeted, “@IndiGo6E systems/servers are down at @bengaluruaiprt.we (passengers) are waiting in long que since almost an hour now. The entire indigo checkin counters are jam packed..@IndiGo6E please update and help (SIC).”

IndiGo, in a statement, said that the server at Bengaluru airport was down between 4.29 am and 5.07 am this morning due to some technical reasons. They also mentioned that the server is restored now and is functioning normally. They reportedly said in the statement that they regret the inconvenience caused to the passengers.

Due to a similar glitch in Air India’s server -- SITA -- in April, more than 155 flights were delayed globally. Passengers were stranded at domestic and international airports.
