Overview

  • Operations slowed from late Thursday after the Automatic Message Switching System malfunctioned, interrupting automatic flight-plan distribution to controllers.
  • The Airports Authority of India said controllers are preparing flight plans by hand while ATC, DIAL and technical teams work to restore the system.
  • Flight-tracking data showed average departure delays of about 45–60 minutes, with reports ranging from more than 100 to nearly 300 flights delayed.
  • IndiGo, Air India, SpiceJet and Akasa Air issued passenger advisories, urging travelers to check flight status as staff assist on the ground and onboard.
  • The disruption created gate and runway congestion at India’s busiest hub and produced knock-on delays at other northern airports handling linked schedules.
