bhai jan aysa nhi hota its called air routes and there is proper system to run them
route # P518 was open some days ago i was watching it indians afghans ME5 everyone was using it
now they opened M504 which is over sindh .which is ALPOR AND TELEM in fact two routes in pakistan .
we will open one by one rest of 9 routes too so air traffic controllers can manage it properly . don't expect all of the entry points open at same time i think every 2-3 days they will keep adding one more route .
in my idea P757 will be next as its major route for east bound flights
