Pakistan’s Airports Authority (PAA) issued a NOTAM on Saturday announcing temporary changes to certain flight routes serving the Karachi and Lahore regions. The restrictions take effect at 5:01am PKT on Tuesday, October 28, 2025, and are scheduled to remain in place until 9:00am PKT on Wednesday, October 29, 2025 — a measure the PAA described as “routine” and needed for “operational reasons” to ensure safe and effective air-traffic management.

Though the PAA did not specify a reason beyond operational safety, the timing has coincided with an Indian NOTAM for a major tri-services exercise — dubbed Trishul — scheduled to run from October 30 to November 10 (or 11, depending on reports) in areas stretching from Rajasthan’s Jaisalmer to the disputed Sir Creek marshes along the western frontier. Open-source analyst Damien Symon shared maps and warned the exercise area and altitude closures were unusually extensive. Firstpost+1
India’s “Trishul” exercise and the Sir Creek focus
Indian outlets and analysts say Trishul will involve the Army, Navy and Air Force and will test joint operations that include amphibious, desert and maritime manoeuvres as well as multi-domain capabilities such as ISR (intelligence, surveillance & reconnaissance), electronic warfare and cyber operations. Indian officials have framed the exercise as a demonstration of growing joint operational capability and preparedness. Firstpost+1
Sir Creek has long been a flashpoint between the two neighbours because of unresolved maritime and boundary claims. The prospect of large-scale drills near this sensitive area has predictably raised concerns in Islamabad and among regional observers. Firstpost
Pakistan bolsters maritime readiness — new hovercraft inducted
Against this backdrop, Pakistan’s naval leadership staged a high-profile visit to forward positions in the Creeks Area. Chief of the Naval Staff Admiral Naveed Ashraf reviewed operational preparedness and oversaw the induction of three 2400-TD hovercraft into the Pakistan Marines — platforms Pakistan says are well suited to the shallow, marshy and multi-terrain littoral zones of Sir Creek and adjacent coastal areas. The navy described the hovercraft as enhancing rapid-response and amphibious capabilities in areas where conventional craft struggle to operate. Dawn+1
Admiral Ashraf emphasised that maritime security and sea-lines-of-communication are crucial to national sovereignty and economic stability, reiterating the navy’s readiness to defend Pakistan’s maritime frontiers “from Sir Creek to Jiwani.” The induction was presented as part of a broader push to modernise littoral forces and improve deterrence along vulnerable coastal sectors.

Political and military context: a tense backdrop
The airspace notices and naval activity come amid elevated India-Pakistan tensions that escalated earlier this year after the May cross-border incidents and subsequent operations that drew international attention and a U.S. diplomatic push for a ceasefire. Indian political and military leaders have since issued robust statements, while Pakistan’s military has warned any fresh hostilities would be met with decisive response, raising concerns among analysts about the risk of miscalculation around high-visibility exercises and warnings.

What this means for travellers and regional watchers
For commercial carriers and travellers, the PAA NOTAM is a short, targeted disruption: airlines operating to and from Karachi and Lahore should consult official NOTAM channels and their operations desks for reroutes and timing. For policymakers and defence watchers, the series of notices and new naval platforms signal heightened vigilance and a period of closely watched manoeuvres on both sides of the border that could shape regional posture over the coming weeks.

Bottom line: Pakistan’s temporary flight-route restrictions (Oct. 28–29) are officially framed as operational safety measures, but they arrive just as India prepares a large tri-services exercise near Sir Creek — prompting diplomatic, military and aviation attention and coinciding with Pakistan’s own moves to reinforce littoral defence capabilities.
