Route notes
Why this routing works
This routing keeps the flying simple by using one arrival point and a different departure point within Pakistan. Starting in New York City, the ticket flies into Islamabad, leaves the surface segment between Islamabad and Lahore off the air ticket, and then resumes with the long-haul return from Lahore to New York City.
That open-jaw structure is useful when the trip moves overland between cities, since it avoids backtracking to the original arrival airport. With a total trip length of 3 weeks, the schedule leaves room to handle the ground transfer between Islamabad and Lahore without compressing the international flight timing.
In economy class, the fare range of $912 to $1,391 places this as a straightforward multi-stop ticket rather than a more complex round-the-world build. August departure timing falls within the July to September travel window provided for this itinerary, so the routing is framed around a late-summer departure and a direct return to the origin city.
