The airport handled 2,392 international flights -- including landing and takeoffs -- in the first two months of 2009, down by 0.29 percent, whereas frequency of domestic flights, including landing and takeoffs, went up by 0.76 percent to 9,824 in the same period.

In the months of January and February 2009, NAC made 345 flights, Indian Airlines 310 and Jet Airways 217.

One of the few countries Nepal surpasses is Sri Lanka. According to 2006 figures, Bandaranayake International Airport of Sri Lanka handled 33,395 flights, around four aircraft per hour.
