New Delhi: Several Air India international flights – mostly Boeing 787-8 Dreamliner – were cancelled on Tuesday, days after the London-bound Boeing 787-8 Dreamliner aircraft crashed into a hostel complex shortly after takeoff from Sardar Vallabhbhai Patel International Airport in Ahmedabad on June 12, killing 241 passengers and crew.

Air India flights cancelled on Tuesday are:

AI915- Delhi to Dubai - B788 Dreamliner

AI153- Delhi to Vienna - B788 Dreamliner

AI143-Delhi to Paris - B788 Dreamliner

AI159-Ahmedabad to London - B788 Dreamliner

AI170- London to Amritsar - B788 Dreamliner

AI133- Bengaluru to London - B788 Dreamliner

AI179- Mumbai to San Francisco - B777

Air India said on Tuesday that its flight from Ahmedabad to Gatwick in London has been cancelled due to the unavailability of the aircraft, resulting from airspace restrictions and additional precautionary checks.

The airline denied claims that the flight has been cancelled due to any technical snag.

Paris-bound Air India flight 143 from Delhi was also cancelled on Tuesday after pre-flight checks identified an issue, which was currently being addressed, an Air India spokesperson confirmed.

The AI143 has been cancelled because the flight is subject to restrictions on night operations at Paris Charles de Gaulle (CDG) airport. "We regret the inconvenience caused to our passengers and are making alternative arrangements to fly them to their destination at the earliest. We are providing hotel accommodation and also offering full refunds on cancellations or complimentary rescheduling if opted by the passengers," an Air India spokesperson said.

Meanwhile, an Air India flight from San Francisco to Mumbai, with a scheduled stop in Kolkata, was grounded on Tuesday after a technical issue was suspected during a routine post-landing inspection. All passengers were safely deplaned, and some have been accommodated in a hotel in Kolkata.

The termination led to chaotic scenes at the Netaji Subhash Chandra Bose International Airport in Kolkata as the 211 passengers on the Boeing 777-200 LR tried to convince officials to let them reach their destination at the earliest.

There were 228 people on board the aircraft, including pilots and crew. The flight was originally scheduled to depart to Mumbai from Kolkata at 2am on Tuesday.

Also, two Dreamliners operated by Lufthansa and British Airways - flying from Frankfurt and London to Hyderabad and Chennai - were forced to return to their origin airports.
