Nepal Airlines Corporation (NAC) dispatched its Boeing 757 to Kolkata to airlift the aviation turbine fuel (ATF).
The Boeing made two rounds to Kolkata, NAC officials said.
This is possibly the second time when Nepal airlifted fuel from India, after 1989 when then Royal Nepal Airlines had made a similar airlift from Bangladesh to keep the kitchen fires burning after its southern border with India was sealed.
Only a fuel tankers of fuel and cooking gas have managed to entered Nepal from India over the past couple of weeks because of the protests near the main border points.

NAC spokesperson Ram Hari Sharma told local media that after the Boeing is defueled, it would be sent back to conduct its regular services on the Kuala Lumpur and Doha sectors.
"Defueling the aircraft will yield at least 20 tonnes after leaving enough in its tanks to conduct its regular flights," he added.
"This will help NOC to boost its reserves. We can airlift more fuel as per the government's order and need."
The daily fuel requirement of domestic carriers amounts to 50 tonnes. Sharma said NAC planes would not be transporting other fuels like petrol, liquefied petroleum gas and diesel.
