See 2072 metres Runway is anyday a joke for an International Airport. It is not even 7000 ft. Forget anything except A320 & B737 which is mainly for domestic operation.
There is a reason that Central Govt wants to develop Bihta as an International Airport. One thing I would like to tell you that the current runway length of Bihta Airport is 8200 ft but still Ministry of Civil Aviation wants additional 191.5 acre of land,just to increase the runway length to 12000 ft. And the reason they mentioned is that they want to make Bihta Airport capable to handle flights like B777 & B787. And that is what I meant by "bade flights" which PAT can never operate.
