Thousands of passengers have been left stranded as 600 Air India pilots take industrial action against their employer.

Over 20 flights in and out of Mumbai have been cancelled, following a decision to walk on strike for a second day.

The striking pilots, owing allegiance to the Indian Commercial Pilots Association of the former Indian Airlines, which merged with Air India later, have struck work demanding parity in pay with Air India pilots and other issues related to work conditions. An Air India spokesperson said, “The management has mustered all available resources to minimise the impact on the scheduled operations.

“While some flights from the major metros have been affected, most of our flights have been operated.”

The airline has offered full refunds to passengers whose flights were cancelled.
