Due to this, over 120 domestic departures have been affected, airport sources said, adding, "by the time the work gets completed, airlines' on-time performances will go for a toss, as the main runway will remain unavailable between 9 am and 5 pm till February 7".

They further said, "In the past two days, every airline has experienced a delay of up to 30 minutes as all the take- offs are now taking place from the 09-end of the main runway 09/27 due to the glide path relocation."
