Air India B777‑200LR returns to Delhi after 7+ hours en route to Vancouver — wrong aircraft lacked Canadian clearance
An Air India Boeing 777‑200LR en route from Delhi to Vancouver returned to Delhi after more than seven hours aloft with 185 passengers when the airline discovered the aircraft lacked Canadian clearance for that airframe. The carrier said an administrative aircraft‑assignment error caused the diversion; the flight later departed for Vancouver.
