Flight Time UK to Australia: 2,400 Travellers Weigh In

Last reviewed: May 2026

There's a moment around hour 11 of a flight to Australia when most British travellers can't help but wonder - "What on earth possessed me to think this was a decent idea again?"

Then you land in Sydney, Melbourne, Perth, or Brisbane, step outside into the bright sunshine in the middle of a freezing British winter, and suddenly the whole thing makes a lot more sense.

Flights from the UK to Australia are some of the longest mainstream routes going - but what we found after digging through data from over 2,400 real travellers was that it's not the length of the journey that gets you - it's how different people handle it.

Some people swear by Singapore stopovers. Others reckon Dubai does the trick best. Some manage the jet lag in two days flat, while others are practically broken for nearly a week after landing.

So instead of giving you yet another generic 'UK to Australia flight time' guide, we took a closer look at what real travellers actually went through - from the routing options they chose to the stopovers they preferred, how they managed jet lag, and what they really wish they'd packed before leaving.

This article was put together independently by us at Simify for informational purposes only. And just to be clear - Simify isn't affiliated with any airlines or airports mentioned in this guide.

So what is the average flight time from the UK to Australia then?

The honest truth is: it's longer than you think, but usually easier than you expect.

The thing is, flight times are all over the place - they depend on where in Australia you're heading and the route you take, not to mention any layovers you might have, and which airline you fly with.

Route	Approx Total Travel Time
London to Perth	16–18 hrs
London to Sydney	21–24 hrs
London to Melbourne	21–25 hrs
Manchester to Sydney	22–26 hrs
Birmingham to Brisbane	23–27 hrs

London to Sydney is usually around 23 hours with a stopover, and one-stop flights to Sydney, Melbourne, and Brisbane usually total 22-26 hours.

Perth's a bit of a special case now that there are direct flights available. Just 17 hours on Qantas, making it by far the fastest option.

But for most travellers heading to Sydney, Melbourne, or Brisbane - one stop is still the norm. The cheapest flights and the lowest prices are usually found in the cheapest months - May, August, September, and sometimes November - while September to November and March to May are a bit more popular.

And honestly, most of the travellers we surveyed said the stopover was almost as important as the airline itself. If you want to save some cash - book and plan in advance, probably about 6 weeks before you fly - and Tuesday, Wednesday, and Saturday are often the cheaper days to depart.

Which stopover route did travellers prefer for the cheapest flights?

This was one of the most interesting bits of our survey.

Out of 2,400 UK travellers, most people still went for the one-stop option, and three stopover hubs stood out as the most popular:

Stopover City	Traveller Preference
Singapore	Most preferred overall
Dubai	Strong second
Doha	Fastest-growing option

Singapore really stood out for its airport comfort, food, cleanliness, and 'reset button' during the journey.

Travellers repeatedly said that Singapore felt calmer and less hectic after ultra-long flights.

Dubai scored highly for the availability of flights and the range of airlines you can choose from. Many liked the flexibility of Emirates and the shorter first leg, compared to Southeast Asia stopovers.

Doha also got some great feedback - especially from travellers flying with Qatar. Many said that Hamad International Airport was smoother and less stressful than they expected.

Hong Kong is also a common stopover, and these routes usually bring you in around 22-26 hours.

What was interesting was that very few people actually chose stopovers based on price alone. Comfort and timing were a lot more important, and many picked the option that helped them catch the best connection.

Are there direct flights from London to Sydney right now?

Not currently, and no, we haven't seen any in commercial operation yet.

There have been some ultra-long-haul demo flights, and airlines are still talking about introducing direct London to Sydney routes in the future - but for now, most UK travellers still stop somewhere in the Middle East or Asia.

The closest thing we have to a 'direct-ish' route is London to Perth with direct flights on Qantas at around 17 hours.

Meanwhile, flights to Sydney, Melbourne, and Brisbane usually require one or more stops. Perth's the only place where you'll stay on the same plane the whole time.

And according to our survey - people either loved the simplicity of non-stop travel or absolutely loathed being stuck on a plane for that long without a proper break. There didn't seem to be much in between.

Qantas vs British Airways vs Middle Eastern airlines

One thing that became super clear from traveller feedback : airline choice is a huge deal on Australia routes.Major UK airlines operating on UK-Australia routes - like Cathay Pacific, Etihad Airways & Singapore Airlines alongside Qantas, Emirates, Qatar Airways, & British Airways - all have a lot of experience with long-haul business flights.

Because these flights are 15+ hours long, little things that might not be a big deal on shorter flights become much more noticeable - like the comfort, service and food.

Qantas

Qantas got top marks for the overall experience on the Perth route. Passengers were consistently happy with their sleep quality and the overall pace of the flight.

Emirates

Emirates stood out for its flexibility with routes and airport experience through Dubai. A lot of passengers liked breaking up the journey into manageable chunks.

Qatar Airways

Qatar scored very highly for comfort, food and the quality of the in-flight service - especially with regular long-haul flyers.

British Airways

British Airways reviews were more mixed. Some passengers liked the familiarity of the flights and being able to get a direct flight from the UK, while others thought that Middle Eastern and Asian airlines handled long-haul travel much better.

Interestingly, it turned out that passengers were much less bothered about luxury than you might expect. What really mattered was seat comfort, flight timing, sleep quality and how pleasant the airport experience was.

How bad is jet lag after Australia flights?

Well, to be honest, it can be pretty bad for many people.

But in a positive twist, the survey found that most passengers adjusted much faster than they expected. Eastbound flights from the UK are often a bit faster too because of the jet stream.

Jet Lag Recovery Time	% of Travellers
1–2 days	28%
3–4 days	47%
5–7 days	21%
More than a week	4%

The big difference in time between London and Australian cities is a big part of why it can take so long for the bodyclock to adjust.

The passengers who adjusted the fastest all shared a few things in common:

• They usually slept well on the flight
• They stayed awake until local bedtime after landing
• They got some sunlight after arriving.

One other thing became clear from the survey: passengers who stopped over somewhere like Singapore or Dubai on their way often said they felt less jet lag than those who did the ultra-long-haul flights without a stop.

Breaking the journey into chunks seemed to make a psychological difference.

What passengers most regretted not bringing

This bit of the survey got unexpectedly emotional.

After 20+ hours of airports and flights, even little things that passengers had forgotten to bring became really important.

The most common things that passengers wished they had brought were:

• Compression socks 
• Good neck pillows
• Downloaded shows on Netflix
• Power banks
• Noise-cancelling headphones
• Refillable water bottles
• Comfortable layers for when the plane temperature changed.

But what really came as a surprise was just how much people wanted to be connected as soon as they landed. Between getting around the airport, using ride apps, getting directions to their hotel and messaging family back home, people relied a lot on their mobile data within minutes of landing.

For travellers heading there: Australia eSIM plans

A lot of passengers specifically mentioned how nice it was to avoid those airport SIM queues after spending all day travelling.

UK travellers should check the entry rules for Australia if they are due to visit for tourism or a short business trip - including if they need an Australian eVisitor visa.

Which Australian city is easiest to fly into?

Perth stands out as being the easiest physically.

The direct London to Perth route made the whole journey dramatically less exhausting than the long-haul flights to the eastern cities of Australia.

But Sydney came out as the most popular destination overall in the survey, closely followed by Melbourne. Some passengers use Perth as a more manageable first stop before continuing on to explore other parts of Australia.

Interestingly, passengers flying into Brisbane often reported worse jet lag, which was probably because the domestic connections added so much to the overall journey time.

One thing a lot of passengers said afterwards: Australia looks much closer on maps than it actually is.

What surprised passengers most about Australia flights?

A few themes came up over and over:

First: passengers found it so much easier once they accepted that the journey would basically take up a whole day. Fighting with reality just made things worse.

For example, a 90-minute connection can still make the total travel time 22 hours or more, while longer layovers can take it right up to 30 hours.

Second: airport quality was a lot more important than passengers expected. A good stopover airport really made a difference to how they felt arriving in Australia.

Third: getting connected immediately after landing cut down on stress levels dramatically. Navigation, transport, hotel details and family updates all got sorted through mobile data almost instantly.

And finally: most passengers said that Australia felt "worth the flight" a lot faster than they expected once they finally got there.

Is premium economy worth it for Australia?

This one came down to a pretty clear yes-no, but the no's were vanishingly rare.

Passengers who paid for premium economy said they would definitely do it again for the Australia routes specifically.

The extra space, better sleep and reduced exhaustion after arrival made a huge difference on flights this long.

Interestingly, a lot of passengers who would never normally consider paying for upgrades said that Australia was the one route where it really changed the experience for the better.
