An IndiGo aircraft from Amritsar missed the exit taxiway after landing at the Delhi airport, impacting flight operations. Due to low visibility, the aircraft was unable to move to the taxiway as instructed by the air traffic controller. A towing tractor was used to tow the aircraft to a parking bay, allowing normal operations to resume. IndiGo spokesperson attributed the incident to low visibility and expressed regret for any inconvenience caused.
