Overview
- India issued a fresh NOTAM on August 22 extending its airspace closure to Pakistan-registered and military aircraft until 05:29 IST on September 24 (23:59 UTC on September 23).
- Pakistan extended its own prohibition on Indian aircraft via a NOTAM on August 20 for the same period, keeping the mirror restrictions in place for a fifth consecutive month.
- Cirium data indicate roughly 800 weekly flight legs by Indian carriers now require detours to West Asia, Europe and North America, increasing fuel burn and complicating crew scheduling.
- Air India has told the government the detours could cost about $600 million on an annualised basis, and IndiGo has suspended Delhi–Almaty and Delhi–Tashkent due to range constraints.
- The impact on Pakistan’s airlines is limited, with only about six weekly PIA flights typically overflying India, while third-country carriers can continue to use both countries’ airspace.
