Quick summary
Lahore’s CAT IIIB instrument landing system now operates at 50 meters of visibility, as of 15 January 2026 — a lower published minimum than Islamabad’s 75 meters. Yet Lahore lost 22 domestic and international flights on 10 January 2026 with visibility at 150 meters, while Islamabad recorded fewer than five fog disruptions across that December–January window. The airport choice now rests on the ground backup, not the equipment.
The M2 Motorway drive between the two cities is 360 kilometers and about four hours: roughly $62 by taxi or $9 by bus. Fly Jinnah’s twice-daily, 45-minute Islamabad–Lahore flight, 14 a week as of July 2026, is the only direct link — and the backup that keeps either booking reversible.
On 10 January 2026, dense fog disrupted operations at Allama Iqbal International Airport in Lahore. The Nation reported 22 domestic and international flights delayed or diverted as runway visibility fell to 150 meters. Islamabad International Airport recorded fewer than five fog disruptions across the same December–January window. The winter choice rests on what happens when a flight does not land, not just the landing equipment.
Better equipment does not settle the choice.
For arrivals from London, Dubai or the Gulf, the backup can mean a road transfer from Islamabad or a domestic hop. The flight returns you to the fog-prone airport you were trying to avoid; the road adds a drive at the end of a long-haul journey.
Islamabad or Lahore airport for winter flights
The security picture does not separate the airports: both moved to Level 3 in the advisory picture. This is a schedule trade-off, not a safety one. A fixed date in Lahore makes a disrupted arrival cost you the day you flew for. With a week in hand, the cost is a hotel night and some patience.
Islamabad is not the safer airport. Its ground backup is the distinction: an airport disruption need not end the journey there.
The old equipment argument has changed, too.

The ILS surprise that changed the old math
The old case for Islamabad rested on its equipment. The assumption was that Lahore’s landing system gave out in heavy fog while Islamabad’s kept aircraft coming in. As of 15 January 2026, Lahore’s Allama Iqbal International Airport (LHE) has a CAT IIIB instrument landing system that operates at 50 meters of visibility. Islamabad International Airport’s (ISB) CAT IIIB handles 75 meters, giving Lahore the lower published minimum.
The disruption record runs the other way.
The visibility during Lahore’s disrupted January operations was above both airports’ published minima. Those minima describe what an airport can do in theory; the winter record describes what happened to passengers.
The distinction is narrow but real. Lahore’s ability to land aircraft in fog is no longer the reason for a detour; the cost of a missed arrival day remains the question.
The M2 road transfer: 360 km, four hours
The M2 Motorway between Islamabad and Lahore is a 360-kilometer, four-lane divided highway. The drive typically takes about four hours.
The motorway has its own winter risk. Pakistan’s Meteorological Department publishes a highway fog update covering the routes out of Islamabad.
The trade-off is comfort against certainty, with fares charged in different ways. A car fare covers the vehicle, however many of you are in it; the bus fare covers a seat. The drive at the end of a long-haul flight is the real cost. That is why some travellers use an open-jaw itinerary into Islamabad and out of Lahore, which removes the return leg across the motorway altogether.
Cost math: transfer versus fare difference
The ground transfer is the fixed part of the cost. The other part is the airfare difference between the two airports, which changes with your dates.
A lost arrival day has a value, too. The comparison is between that loss and the extra cost of arriving through Islamabad, not simply between two ticket prices.
PIA has allowed free rebooking for weather disruptions up to 72 hours before departure. That makes a Lahore ticket less than a permanent bet, but the window closes three days out. A switch has to be a decision made before check-in, not a reflex there.
Backup: domestic flights and winter schedules
Fly Jinnah’s Islamabad–Lahore nonstop launched on 1 May 2026, according to Profit by Pakistan Today. It remains the only direct link between Pakistan’s two northern gateways, with 14 flights a week as of July 2026. The flight takes 45 minutes.
It solves the motorway, not the fog.
Lahore has not become a minor airport. According to the airport’s own route list, 28 airlines operated scheduled passenger flights there as of May 2026. Dubai is the busiest international route, and PIA flies year-round to London Heathrow. For the winter ahead, PIA plans seven weekly Heathrow flights: five from Islamabad and two from Lahore.
Before the winter timetable and the fog
Lahore’s fog season runs through December and January. The planning decisions belong before check-in, while there is still time to change the booking if the forecasts turn.
- Price both airports on your own dates in Google Flights, then add about $9 (bus) or $62 (taxi) to the Islamabad total before comparing.
- Hold a fallback on the ground: Daewoo Express leaves every 30 minutes at PKR 2,500 (about $9), while the domestic flight has one operator and two daily departures.
- Check the highway forecast through the Met Office fog update for the Islamabad–Lahore route on the morning you travel.
- Watch: publication of PIA’s winter timetable — the Islamabad and Lahore split of its Heathrow flights will show where the airline expects the season to run.
The winter timetable takes effect on 27 October 2026. The first real test of Lahore’s new landing minima arrives with the first fog of December.

Questions? Answers.
How do I book ISB-to-Lahore ground transport in advance?
Departures are frequent enough that pre-booking is rarely necessary: Daewoo Express buses leave every 30 minutes at PKR 2,500 (about $9) for the 4.5-hour run. If you want a car instead, plan around the apps — Uber stopped operating in Pakistan in April 2024 and Careem closed in July 2025, leaving InDrive as the current reliable option.
Is the M2 Motorway safe to drive at night during fog season?
The M2 is a 360-kilometer, four-lane divided highway with a typical transit time of four hours, and it is the main artery between Islamabad and Lahore rather than a back road. The variable is fog on the Punjab plain, which is why the Meteorological Department issues a highway update — and on a bad night the 45-minute domestic flight is the substitute.
Can I claim compensation if my Lahore flight is diverted due to fog?
PIA has allowed free rebooking for weather disruptions up to 72 hours before departure, which is the practical protection rather than a payout. Because that window is set by the airline’s policy and not by the weather, confirm your own fare rules before you book.
Does Lahore still work for long-haul arrivals?
Yes. PIA began a direct Lahore–London service on 30 March 2026, roughly eight hours, and moved its Heathrow operation to Terminal 4 on 29 March 2026. With seven weekly Heathrow flights planned for the coming winter, both Pakistani airports will have London service in the 2026–27 season.
