It was then diverted to Lucknow, but poor visibility in the U.P. capital forced it to head to Prayagraj, and then again re-route to Lucknow, where it landed after the pilot gave a call for a fuel May Day. The plane landed at Lucknow at 6.49 p.m., nearly two hours after its scheduled time of arrival at Delhi. When the aircraft landed it had 300 kg of aviation turbine fuel, enough for 10 minutes of flight. A flight from Lucknow to Delhi finally left at 12.15 a.m. to ferry the passengers to their destination.
