Qantas Reroutes Perth-London Via Singapore After 45-Minute Detour

Qantas rerouted qantas flight QF9 from Perth International Airport to London Heathrow Airport via Singapore after Middle East airspace closures added up to 45 minutes to the trip. The move pushed the journey to more than 20 hours and gave the airline room to carry more than 60 additional passengers per flight.

March 25 2018 Route

March 25 2018 marked the start of direct non-stop flights between Australia and Europe, with Qantas becoming the first airline to do it on the Perth-London link. The route has run as QF9 and QF10 on a Boeing 787-9 with 236 seats, including 42 in business class, 28 in premium economy and 166 in economy.

9,000 miles is a long way to cover on an aircraft that Boeing officially lists at 8,705 miles of range. The gap left the service close enough to the aircraft limit that even a modest increase in distance could force a different routing.

October 2024 Capacity

219 seats per flight was the westbound average between October 2024 and September 2025, with 16 seats empty on average. The eastbound return from London had only one seat empty on average in that same period, showing how tightly the route had been filled before the detour.

45 minutes of added flying time from the 2026 Iran Crisis exceeded the margin needed to keep the Europe-bound leg nonstop. Qantas had already routed the service via Singapore twice in 2024 for similar reasons, and the new QF209 routing again uses Singapore Changi Airport to make the trip work under the longer path.

QF209 Through Singapore

More than 60 additional passengers is the practical gain from the Singapore routing, but it comes with a longer journey and a different product for travelers booked on the service. For passengers on the Perth-London link, the change means the nonstop model that defined the route since 2018 no longer holds when Middle East airspace closures add enough distance to strain payload limits.
