Quick summary
Qantas suspended its nonstop Perth–London QF9 service from 4 March 2026, rerouting it as QF209 with a stop at Singapore Changi Airport after Middle East airspace closures linked to the 2026 Iran crisis forced a longer northerly detour that exceeded the Boeing 787-9‘s payload limits on the westbound leg. The total journey now runs 20–21 hours, up from 17 hours nonstop, while the Singapore stop removes payload restrictions and restores approximately 60 additional revenue seats per flight.
Only the westbound leg is affected — the return QF10 London–Perth remains a nonstop service. The rerouting is currently filed through mid-July 2026, with no confirmed reinstatement date for the direct flight.
Qantas’ flagship Perth-to-London nonstop — the world’s longest scheduled service when it launched on 25 March 2018 — is no longer flying direct. From 4 March 2026, the westbound service operates as QF209 via Singapore Changi Airport, adding over three hours to a journey that was already pushing the limits of what a Boeing 787-9 can do in a single bound.
The trigger is the 2026 Iran crisis. Airspace closures across Iran, Iraq, Israel, and several Gulf states have shut down the most efficient great-circle path between Australia and Western Europe, forcing a longer northerly routing via India, Pakistan, Afghanistan, and the Caucasus — a detour that adds 30–45 minutes of flight time and enough extra fuel weight to make a full passenger load impossible on a single leg.
Qantas’ answer is Singapore.
By splitting the mission at Changi, each segment falls comfortably within the 787-9’s range envelope. The Perth departure now leaves at 14:25, arrives Singapore at 20:15, departs again at 21:45, and lands at London Heathrow at 05:05 the following morning. Passengers gain a seat — around 60 more per flight are now available — but lose the nonstop convenience that made QF9 one of the most talked-about routes in commercial aviation.
What the rerouting actually means for your booking
The numbers behind this change are worth understanding. In the year to September 2025 — before the 2026 rerouting — westbound seat capacity on the Perth–London sector averaged just 219 seats per flight on a 236-seat aircraft, according to industry data. Qantas was routinely blocking seats to stay within maximum take-off weight. The eastbound return, by contrast, averaged just one empty seat per flight: a near-full cabin, no payload problem, because tailwinds on the London–Perth leg reduce fuel requirements significantly.
That asymmetry is the core of this story. The westbound leg was already operating at the edge of what the 787-9 could do before the Iran crisis made the routing longer. When the efficient path through the Middle East closed, the aircraft simply could not carry a full load and enough fuel to reach London nonstop via the alternative track.

Why this is harder to reverse than the 2024 rerouting
This is not the first time Qantas has made this call. In August 2024, the airline rerouted QF9 via Singapore for roughly two weeks — from 8 to 22 August — as Middle East tensions spiked, then restored the nonstop once risk assessments improved. That episode was explicitly time-limited and resolved quickly, which is why Qantas framed the current situation as “temporary” when it began in March.
The difference now is duration and scope. The 2024 detour lasted 14 days. The current rerouting has been in place since 4 March 2026 and is filed through at least mid-July — over four months and counting. The airspace closures now span Iran, Iraq, Israel, Qatar, Bahrain, Kuwait, and the UAE simultaneously, which is a materially wider restriction than what triggered the 2024 pause. Reopening any one of those corridors helps; reopening all of them is what restores the original great-circle path.
For travelers, the practical read is this: do not plan around a nonstop resumption in the near term. The Singapore stop is the product right now.
Steps to take now if you’re booked on this route
The nonstop QF9 is suspended with no confirmed return date — every westbound Perth–London booking from March 2026 onward is now a two-leg journey, and itineraries built around the old schedule need to be checked today.
- Verify your booking shows QF209: Log into your Qantas booking or the Qantas app and confirm the westbound leg now shows QF209 via Singapore Changi with a 14:25 Perth departure. If it still shows QF9 or the old 18:30 departure, call Qantas directly — the rebooking should be automatic but errors occur.
- Adjust domestic connections into Perth: The earlier departure means a same-day domestic flight from Sydney, Melbourne, or Brisbane that previously worked may no longer connect. Check minimum connection times at Perth International Airport and rebook domestic legs if needed.
- Price alternative routings: Sydney or Melbourne travelers heading to London should compare QF1/2 via Singapore directly against the current two-stop SYD/MEL–PER–SIN–LHR itinerary on qantas.com. Emirates via Dubai and Qatar Airways via Doha are also worth pricing for total journey time.
- Check award seat availability on QF209 SIN–LHR: The Singapore stop creates a bookable Qantas-operated SIN–LHR segment. Asia-based travelers or those with Qantas Points should check this leg against Singapore Airlines and British Airways for award redemptions.
- Monitor NOTAMs and safety guidance: Australia’s Civil Aviation Safety Authority and Eurocontrol are the bodies to watch for any easing of restrictions over Iran and neighbouring states. If advisories are downgraded, a nonstop return becomes operationally viable again.
Watch: Qantas’ Northern Winter 2026 timetable filing will be the clearest signal of intent — if QF209 via Singapore is filed through to March 2027, the airline is effectively normalising a hub-and-spoke Europe strategy via Singapore rather than planning a nonstop revival.
Questions? Answers.
Is the return London–Perth flight also rerouted via Singapore?
No. The return service, QF10, continues to operate as a nonstop from London Heathrow to Perth. Only the westbound Perth–London leg is affected by the rerouting. Eastbound tailwinds significantly reduce fuel requirements, keeping the return flight within the 787-9’s payload limits even on the longer northerly routing.
When will the nonstop QF9 Perth–London service resume?
Qantas has not given a confirmed reinstatement date. The rerouting is described as temporary and under constant review, but the current filing runs through at least mid-July 2026. Resumption depends on airspace restrictions over Iran, Iraq, and Gulf states being eased or lifted — a decision that rests with governments and aviation regulators, not Qantas.
Does the Singapore stop mean I need a transit visa?
Most nationalities do not require a visa for a transit through Singapore Changi Airport if remaining airside, but rules vary by passport. Travelers with certain nationalities or who plan to leave the transit area should check Singapore’s Immigration and Checkpoints Authority requirements before travel. Qantas should handle the transit as a through-ticket, but confirm your baggage is checked through to London Heathrow at check-in in Perth.
Are there better alternatives to QF209 for Perth-to-London travel right now?
Several options are worth comparing. Emirates operates Perth–Dubai–London, Singapore Airlines operates Perth–Singapore–London, and Qantas QF1/2 runs Sydney–Singapore–London for travelers willing to connect via Sydney. Total journey times and fares vary significantly by departure time and booking class — price all three on the same dates before committing.
