Flight operations at Delhi Airport have been disrupted due to a technical problem in the Automatic Message Switching System, which plays a key role in Air Traffic Control flight planning.

"All airline services at the airport are currently affected. The authorities are working to fix the issue as soon as possible," the Delhi airport said in a statement.

The Chhatrapati Shivaji Maharaj International Airport (CSMIA) in Mumbai on Friday clarified that it has withdrawn its advisory regarding disruption in flight services following a technical glitch.

Earlier in the day, the Jaipur airport also witnessed a delay in flight operations following a technical snag.

The AMSS failure at Delhi Airport is now affecting airports in Mumbai, Jaipur, Lucknow, Varanasi, and several other major international airports, as flights departing from Delhi to these locations are facing delays. So far, the Airports Authority of India has not confirmed any technical issue at these other airports.

Mumbai International Airport Limited (MIAL) has clarified that the earlier advisory was issued by mistake due to human error.

The airport authority has now withdrawn that advisory, and flight operations at Mumbai airport are currently running smoothly.

There has been a major problem in the Air Traffic Control (ATC) system at Delhi’s Indira Gandhi International Airport, which has affected the movement of flights. Around 1500 flights operate daily at the Indira Gandhi International Airport.

Due to an issue in the ATC software, the movement of nearly 300 flights has been directly affected. These 300 flights are running with delays of around half an hour to one hour.

Because of the software issue in the ATC server, flight movements are currently being managed manually by ATC staff.

The Lucknow airport too announced a technical glitch concerning the AMSS and operations delay with the Air Traffic Control (ATC), leading to flight delays.

Jaipur Airport authority announced on X about flight operations being impacted in Delhi, Mumbai, Lucknow and Jaipur due to a technical issue with the Automatic Message Switching System (AMSS), which supports Air Traffic Control flight planning. 

AMSS in airports stands for Airport Management System Server (or sometimes Airport Management Support System depending on the airport and vendor).

It is a central software system used to manage and coordinate key airport operations.

What AMSS Does

AMSS typically handles:

• Flight information management (arrivals, departures, delays)
• Gate and stand allocation
• Runway and apron usage planning
• Communication between airlines, ATC, ground staff, and airport authorities
• Real time updates for display boards and announcement systems

The airports in Delhi, Mumbai, Jaipur and Lucknow are currently experiencing a technical glitch concerning the Automatic Messaging Switching System, which has affected Air Traffic Control operations of airlines, causing major flight delays.
