Earlier on January 2, IndiGo made a priority landing in Ahmedabad after smoke was detected mid-air in the cockpit and cabin of the A320 aircraft. The pilot issued a Pan-Pan call and sought a priority landing from the Ahmedabad ATC.
An IndiGo spokesperson said its flight made a priority landing due to an "unusual" smell. A 'Pan-Pan' call is the one which is issued in a less urgent situation but that still requires attention from air traffic control.
