New Delhi: Air safety watchdog, the Directorate General of Civil Aviation (DGCA), has extended the ban on airlines flying Boeing 737 Max aircraft to overflights, too, from 4 m on Wednesday.

"No B737 Max aircraft will be allowed to enter or transit the Indian airspace effective 1600hrs Indian time or 1030 UTC (Universal Coordinated Time). The timeline is to cater to situations where aircraft can be positioned at maintenance facilities and international flights can reach their destinations," the civil aviation ministry said in a post on Twitter.

SpiceJet, which has 13 Boeing 737 Max aircraft in its fleet, cancelled 14 flights beginning Wednesday.

"While a majority of passengers affected as a result of these cancellations have been accommodated by SpiceJet on alternate flights, rest have been offered a full refund. Safety and security of our passengers, crew and operations are of utmost importance to us and we are closely working with the regulator and the manufacturer to resolve the matter, " the airline said in a statement.

It will complete the grounding of Boeing 737 Max aircraft by 4 pm on Wednesday.
