Sydney is the longest journey most of our clients ever take, and the difference between arriving ready for dinner and arriving fit for nothing is almost entirely in how the trip is broken up. London to Sydney is not really one decision. It is the decision about the airport in the middle.
The history is a useful measure of how far the route has come. When Qantas first flew the Kangaroo Route in 1947, London to Sydney took four days and seven stops — Darwin, Singapore, Calcutta, Karachi, Cairo, Castel Benito and Rome. Every generation of aircraft since has taken a stop out. By the 1990s it was one. And in June 2026 Qantas confirmed the last one would go: a genuine non-stop between Sydney and London, on a purpose-built Airbus A350-1000ULR, from October 2027.
That is a real milestone, and we will book it. But it is sixteen months away as we write, the seats go on sale in February 2027, and — this is the part worth saying plainly — the non-stop will not be the right flight for everyone even once it arrives. Twenty-two hours in a single cabin is its own kind of endurance. For now, and for a good while yet, getting to Sydney well means choosing the stop.
The three ways we route it now
Every Sydney itinerary we build runs through one of three hubs, and they are not interchangeable.
Singapore (Changi) is where we send most Australia-bound clients. Qantas flies its own metal Sydney–Singapore–London, Singapore Airlines runs the route on the A380, and Changi is the rare airport that makes the break feel like part of the trip rather than an interruption. In first, The Private Room is the only lounge in the world we tell clients to arrive early for; in business, the facilities are still excellent. Seven or eight hours, a shower, and a second flight beats a single thirteen-hour sector almost every time.
The Gulf (Dubai or Doha) is the alternative when the cabin product matters most. Emirates flies the A380 via Dubai with the best of its business and first hard product; Qatar's Qsuite via Doha is, by most measures, the strongest business seat in the air, and the Al Mourjan lounge is a place you can genuinely rest. The Gulf adds a little distance over Singapore, but for a client who wants the best seat available, it is often where we land.
Perth is the quiet third option. Qantas flies London to Perth non-stop, and Perth to Sydney is a short hop on the far side. It is the closest thing to a direct routing that exists today — one airline, one ticket, the fewest moving parts. For clients who simply want it over with, it is the cleanest answer we have.
The honest case for the stop has never been about time. It is that two flights, with a shower and a flat bed in the middle, are easier on the body than one very long one — and that the body remembers the difference for days.
What the non-stop will change, and what it won't
From October 2027, Qantas will fly Sydney to London without stopping, on aircraft configured for just 238 passengers across four cabins rather than the usual three or four hundred — more room, a cabin designed around sleep and movement, and up to four hours saved against the one-stop. It will be the longest scheduled flight in the world, and for the right traveller it will be a genuine change.
It will also run alongside the Perth and Singapore services, not instead of them. We expect to keep routing a great many clients through a stop even after the non-stop arrives, because the choice between twenty-two hours in one seat and two rested halves is a matter of how your body travels, not which option is objectively better. When the seats go on sale, we will be among the first to know, and we will tell you honestly which suits you.
What we ask before we book Sydney
Four questions, every time. What time do you need to land, and how functional must you be the next day? How well do you sleep on a plane? Do you actually mind a stop — or do you only think you do? And which cabin: a flat bed for the long sector is worth more to Sydney than to almost anywhere else.
The continuity matters too. We keep clients on one airline and one alliance through the stop wherever we can, because changing carrier in the middle is a real step down — a different seat, a different lounge, a different standard, at the precise moment you least want one. Qsuite to Doha then Qsuite onward; Singapore business or first the whole way. The seamless version is almost always worth arranging properly.
The fare, as ever, tends to reward the patient routing — sometimes by enough to move a client from business to first for the money they were going to spend anyway. That is rarely the reason we suggest a particular routing. But on the longest trip there is, it is worth knowing.
