Delhi is the busiest airport in the country and its three runways handle over 1,300 flights daily.
However the number of flights has come down to 800-900 due to cancellations and suspension of operations. Typically 120-130 planes are parked overnight at Delhi and these operate through the day.
"Till now there was no issue like shortage of parking bays. But as airlines have cancelled flights the aircraft continued to occupy the bays and hence one of the runway was made available for parking," said an airport official.
Most of Air India's wide body fleet including Boeing 777 and 787 and planes of GoAir and IndiGo are being parked in Delhi due to reduced operations.
