Dear, I don't think so that there are 2300 seats or never heard such info.
Total seats are 940 approx and can be minimized further after final approval
of PIA MD as the final list has not yet done. I have heard that every day there
is an update in the list due to high ministers source for their favorite candidates.

This is Pakistan man and no fair selection or merit. Most of the seats are distributed to ministers. God Knows whether some of the seats were left
for MERIT or not.
