India, Dec. 5 -- IndiGo on Friday cancelled all its departure flights from Delhi's IGI airport till midnight amid operational disruptions, airport officials told HT. The flight disruptions have largely been owed to new flight duty norms that took effect on November 1 and IndiGo's struggles with implementing the second phase of the Flight Duty Time Limitations (FDTL) norms.

The new provisions limit pilot duty hours at night, and the airline's requirement for pilots-in-command has only been increasing.
