The business week runs in both directions
Government and corporate travellers head north to Islamabad early in the week and return south at the end of it. That makes Monday and Tuesday mornings the expensive northbound departures and Thursday evenings the expensive southbound ones. Booking the southbound leg on a Wednesday or a Friday afternoon rather than Thursday evening is the most reliable saving available on this direction.
Islamabad’s airport transfer works against early departures
Islamabad International is around 25 km from the city centre, and further for anyone travelling in from Rawalpindi’s outskirts or beyond. A cheap early morning southbound departure means leaving before dawn, which is worth weighing against a midday flight at a modest premium, particularly if you are travelling with family.
Connecting onward from Karachi
Karachi has the deepest international network in the country, and PIA lets you book a domestic sector and an onward international flight on a single ticket. If your journey continues beyond Karachi, that protects the connection if the first leg runs late, which two separate tickets do not.
