Delhi's Indira Gandhi International Airport (IGIA) on Friday stated that the matter is being addressed as a priority, with close coordination among ATC, DIAL, and other stakeholders, following delays to at least 100 flights caused by a technical issue in the Air Traffic Control (ATC) system.

AAI added that controllers are currently processing flight plans manually, resulting in further delays.
