A NOTAM published on the Air Traffic Flow Management portal of the Airports Authority of India (AAI) restricted non‑scheduled flight operations at airports within a 300‑kilometre radius of New Delhi from September 11 through 13, 2026, in roughly the 07:00–23:00 IST period on those days. The published measures exempted regular scheduled commercial airline services and specified authorised flights, while principally targeting private, non‑scheduled and charter operations.

The airspace measures allowed flights that had prior authorisation, including VVIP and diplomatic delegations, state aircraft and certain security, emergency and approved missions. Safdarjung Airport and some smaller heliports and airfields were reported closed to normal civil operations during the restriction window, with only specified Indian Air Force, Border Security Force, National Security Guard or other authorised helicopter movements permitted.

Northern Railway issued operational revisions for the Delhi/Northern Railway area covering September 11–13, announcing cancellations, diversions, short terminations/origins and rescheduling that affected a broad set of local EMU/MEMU services and many long‑distance trains. Several premium long‑distance services — including Rajdhani and Tejas Rajdhani trains and some Vande Bharat and other express services — were listed among services to be diverted, rescheduled or regulated during the three‑day window.

In the city, practical effects included cancelled and regulated EMU/MEMU local services and planned regulation or delays to selected long‑distance trains, producing commuter disruption and advisories to check live train status before travel. Northern Railway’s published statement framed the train changes as due to operational reasons and did not explicitly cite the BRICS summit, though the three‑day window coincides with the summit dates.

The Delhi Metro Rail Corporation announced that metro services would commence at 06:00 on Sunday, September 13, to facilitate movement of exam candidates and commuters amid the wider traffic restrictions. Delhi Traffic Police and city authorities issued traffic advisories and regulated vehicular movement on key central stretches during September 11–13 to secure summit venues; emergency and essential services were to be permitted while commuters were warned to expect diversions and delays.

Authorities and transport operators implemented coordinated measures across air, rail and road networks for the three‑day window, with exemptions and authorised movements maintained alongside closures and route adjustments aimed at securing summit venues and managing city movement.
