While extending the Pakistan visas at the passport immigration office, Islamabad .

I wouldn't personally turn up at the airport if I was more than a month overstayed, just asking for trouble. So I have to agree that the OP should go straight to his nearest passport/immigration office and try to resolve this before he attempts to leave the country.

The Pakistan interior ministry these days introduced some very strict rules towards the foreigners .

No one seems to know whether overstay fines can be paid at Pakistan airports on departure like countries in Philippine, Thailand. On DGIP website its not clearly mentioned where the fine can be paid. I am in Quetta and its not safe to go to passport office as Quetta is marred by violence on particular ethnic and religious group and this is the reason I couldn't extend my visa at first place. I have overstayed by more than three months.

Are you planning to fly from Quetta or what is your next destination in Pakistan so you could extend your visa there ?

I haven't planned yet but I prefer to fly from Quetta to Dubai. Flying to Karachi or Islamabad means I have to stay few days before leaving.
shandur_adventure, are you sure fines can be paid at the airports?
Am sure yes,where else you think you pay the overstay fine?You pay the fine at immigration desk while leaving.
