Flying long-haul doesn’t have to mean paying premium prices. From routing through China or Vietnam to using secondary airports such as Bordeaux or Newcastle, changing where you fly through can dramatically reduce the cost of international travel.
For years, travellers looking for a cheaper airfare have been conditioned to do the same things: change the date, change the airline, fly midweek, book earlier, or sacrifice a direct flight. But there’s another strategy that can make a surprisingly significant difference, particularly if you’re searching for cheap long-haul flights from Australia to Europe or the UK. Change the airport.
Not necessarily the airport you ultimately want to arrive at, but the airport you depart from, connect through, or use as your gateway into a region.
Quick summary — if you only remember one thing: before you book, run the same search through at least three different connecting hubs and two different arrival airports. It takes five minutes and can save thousands on a long-haul Business Class fare.
Why the “obvious” route usually costs more
This matters particularly for Australians flying to Europe, where the obvious routing is not always the best-value routing. Sydney–Singapore–London, for example, is one of the most familiar ways to travel between Australia and Britain. Singapore Changi is also one of the world’s best airports, which makes it an easy default.
But default routes attract enormous demand — and demand drives price.
Search Sydney to London via Singapore, Dubai or Doha, then run the same search through Hanoi, Ho Chi Minh City, Guangzhou or Beijing, and an entirely different set of fares, airlines and inventory can appear. There’s no guarantee the alternative will be cheaper on every date, but it’s increasingly worth checking.
The skill in booking long-haul travel today is no longer simply knowing which airline to search. It’s understanding how airline networks work.
How airline pricing actually works (and why the connecting city matters)
Airfares aren’t calculated simply according to distance. Airlines price seats according to demand, competition, available inventory, fare classes, connecting traffic, and what they believe passengers in a particular market will pay.
That’s why two journeys of roughly comparable length can have dramatically different prices.
A heavily travelled Australia–London itinerary through Singapore may have strong demand from corporate travellers, families and premium leisure passengers. Another airline trying to fill seats through Guangzhou, Hanoi or Beijing may price the journey far more aggressively to compete.
Google Flights itself actively encourages travellers to look beyond a single airport. Its flight-search tools allow multiple origin and destination airports to be entered simultaneously, while its Airports feature highlights occasions when using another airport may reduce the fare. Its Cheapest tab can also surface combinations involving different airports, or separate tickets, that wouldn’t necessarily appear among the most convenient results. (Google Help)
For a long-haul traveller — particularly one buying Business Class or Premium Economy — the difference can become substantial.
Cheap flights to London from Australia: don’t automatically fly through Singapore
For Australians, Singapore has become almost psychologically attached to European travel. And there are good reasons for that. Changi is efficient, comfortable, exceptionally well organised, and one of the most pleasant places in the world to spend a few hours between flights.
But convenience and price are not always the same thing.
When searching Sydney, Melbourne or Brisbane to London, I would now compare at least:
- Singapore — still the benchmark for convenience, particularly with Singapore Airlines and its partners
- Hong Kong — often worth testing for Cathay Pacific and connecting fares into Britain and continental Europe
- Guangzhou — one to watch when searching China Southern and China–Europe combinations
- Beijing — particularly interesting for Air China and other Star Alliance possibilities
- Shanghai — another major Chinese gateway, but don’t assume Shanghai and Beijing will price identically; search them independently
- Hanoi and Ho Chi Minh City — Vietnam deserves far more attention from Australian travellers. Vietnam Airlines’ current network includes Sydney and Melbourne services into Vietnam as well as London services from Hanoi and Ho Chi Minh City, making Vietnam a legitimate Europe gateway rather than simply a holiday stop. (Vietnam Airlines)
- Kuala Lumpur — another city routinely overlooked by travellers automatically searching Singapore
- Bangkok — particularly useful if you’re prepared to compare separate tickets as well as through-fares
- Dubai, Abu Dhabi and Doha — the established Middle Eastern hubs remain extremely useful, but because Australians search them so frequently, they shouldn’t be the only alternatives considered
The point isn’t that Beijing will always beat Singapore, or Vietnam will always beat Dubai. It won’t. The point is to make the airlines compete for your journey rather than deciding your route before you’ve seen the prices.
London isn’t necessarily Heathrow
The same thinking applies at the other end of the journey.
Travellers often type “LHR” almost automatically when searching for London, when London’s airport system actually gives you considerably more leverage: Heathrow, Gatwick, Stansted, Luton and London City can all produce different results.
If London is merely the beginning or end of a larger British trip, go one step further.
Manchester can be useful. So can Edinburgh. And Newcastle is considerably more internationally connected than many Australians realise — Newcastle Airport currently has a daily Emirates service to Dubai, providing onward connections through the Emirates network, as well as services through major European hubs. (Newcastle Airport)
If you’re visiting northern England, Scotland, or places such as Durham, flying into London simply because it’s Londoncan mean paying more for the airfare and then spending additional time and money travelling back north.
The correct question isn’t “How cheaply can I fly to Heathrow?”
It’s “What’s the most efficient and economical gateway for the trip I’m actually taking?”
European gateway airports Australians routinely overlook
The same principle applies across continental Europe.
Paris Charles de Gaulle, Rome Fiumicino and Amsterdam Schiphol are obvious international gateways. But occasionally a smaller or secondary city creates a better itinerary.
Bordeaux is a good example. Bordeaux Airport has more than 80 direct destinations across more than two dozen countries in its summer 2026 network, including British Airways services to London Gatwick, KLM to Amsterdam, Lufthansa to Frankfurt and Munich, and Turkish Airlines to Istanbul, which Turkish specifically markets as a gateway to its wider international network. (Bordeaux Airport)
For someone holidaying in south-west France, flying into Paris and travelling three hours back across the country isn’t automatically logical.
Likewise:
- Heading for Provence? Compare Marseille and Nice.
- Heading for Tuscany? Search Florence, Pisa, Bologna, or even Milan or Rome depending on the wider itinerary.
- Heading for northern Spain? Bilbao may beat Madrid.
- Heading for southern Spain? Malaga and Seville come into the equation.
Think in regions, not airport codes.
Sometimes two tickets beat one
There’s another level to this strategy.
Instead of searching Sydney–Bordeaux directly, for example, you might price Sydney–Istanbul and Istanbul–Bordeaux separately. Or Sydney–London followed by a separate European flight.
Google Flights supports both multi-city searches and, in some results, separate or self-transfer tickets. (Google Help)
This can save money — but it introduces risk.
If the tickets are separate, the second airline generally has no obligation to accommodate you if the first flight is late. You may have to collect and re-check luggage, clear immigration, change terminals, or even change airports.
For that reason, I would never schedule an aggressive self-transfer after a 20-hour journey just to save a few hundred dollars. Build in a generous buffer or, better still, turn the connection into a night or two in another city. A cheaper flight that gives you 36 hours in Hanoi, Beijing or Istanbul can suddenly become part of the holiday, not just a layover.
The five-minute search that can save a long-haul traveller thousands
Before buying an expensive international ticket, I now think it’s worth running several searches:
- Start with the obvious city pair.
- Replace the connection.
- Replace the arrival airport.
- Search the nearest major regional airport.
- Use Google Flights’ date grid and price graph rather than assuming your original dates are fixed.
Google also allows fare tracking and can notify travellers when prices on a selected route change significantly. (Google Help)
For Sydney–London, don’t search one journey. Search ten versions of it:
- Sydney–Singapore–London
- Sydney–Hong Kong–London
- Sydney–Guangzhou–London
- Sydney–Beijing–London
- Sydney–Hanoi–London
- Sydney–Ho Chi Minh City–London
Then compare London Heathrow with Gatwick, Manchester or Newcastle if they make sense for your trip. Do the same in reverse when travelling home.
It takes minutes, yet on a Business Class fare worth several thousand dollars, a different hub, a different European gateway, or a slightly different starting point can materially change the price.
FAQ: Finding cheaper long-haul flights from Australia
Is it actually cheaper to fly to London via Asia instead of Singapore or Dubai? Not always, but often enough to be worth checking. Routes through Hanoi, Ho Chi Minh City, Guangzhou or Beijing can undercut the more heavily searched Singapore and Dubai routings because demand — and therefore price — is lower on those connections.
Which London airport is cheapest to fly into from Australia? It varies by date and airline, which is exactly why it’s worth comparing Heathrow against Gatwick, Manchester, Edinburgh and even Newcastle rather than defaulting to Heathrow automatically.
Is booking two separate tickets instead of one riskier? Yes. If your connecting flights are on separate tickets, the second airline isn’t obligated to rebook you if the first is delayed. Build in a generous layover, or turn the stopover into an overnight stay to reduce the risk.
Does Google Flights show cheaper alternative airports automatically? Partially. Its Airports feature and Cheapest tab can surface alternative-airport combinations, but you’ll still get the most complete picture by manually searching different connecting cities and arrival airports yourself.
