Pakistan Airports Authority posted a new Notice to Airmen on 16 September. Pakistani airspace is not available to Indian-registered aircraft, or to aircraft owned, operated or leased by Indian airlines and operators, including military flights. The notice took effect at 10.45 that morning and runs until 04.59 on 24 October. It covers both the Karachi and Lahore flight information regions. The previous paper was due to die on 24 September. Geo News called this the seventeenth such notice since the first closure on 23 April 2025, after Pahalgam. That count is now the story. Seventeen renewals is not a temporary security measure. It is the operating environment.
Indian westbound metal still cannot fly the short line through Lahore and Karachi. Delhi–London, Mumbai-Frankfurt, Bengaluru-Paris, Delhi-Amsterdam and the North America sectors that once cut across Pakistan now go south and around, or they stop. Air India told Indian officials last October that some long-haul sectors were burning as much as 29 percent more fuel and adding up to three hours. The same paper put the hit to profit before tax at about 455 million dollars a year. Other reporting last year used a rounder 600 million if the ban lasted a full twelve months. Those figures are airline estimates, not a regulator’s audit. They are still the best public numbers on the table. Five more weeks at that burn rate is not a rounding error. It is another month of extra block hours, extra crew duty, extra tanker fuel at technical stops, and extra carbon that no Indian SAF mandate can offset.
The competitive wound is sharper than the fuel invoice. Emirates, Qatar Airways and Etihad still fly the same city pairs through the corridor Indian carriers cannot use. The passenger who books DXB or DOH does not pay the Indian detour tax. Air India tried to solve Delhi-Toronto by changing the aeroplane rather than the map. IndiGo trimmed some Europe flying and dropped Copenhagen. Cargo that used to ride Indian bellyhold has a reason to shift onto Gulf metal that still flies the short track. Parliament was told earlier that about 26000 Indian-carrier international flights had already been touched by West Asian and Pakistani restrictions. That number will keep growing until someone publishes a better one.
Ministry and DGCA have not announced airport-charge relief, extra route rights or a compensation window tied to this extension. Forwarders have not been given a public cargo-time series. Until those arrive, the only honest tracker is the timetable itself. Look at scheduled block time on an Indian metal sector to Europe or North America, then look at the same city pair on a Gulf carrier. The difference is the price of a corridor that has now been closed, on paper, into late October, with no sign that the eighteenth notice will not follow.
