Flying from the United States to Australia is one of the most epic long-haul journeys on the planet. Depending on where in the USA you’re departing from, you’re looking at somewhere between 15 and 23 hours of flying time — one of the longest commercial air routes in regular operation. I’ve done this crossing multiple times from both coasts, and the choice of airline and routing makes an enormous difference.
The good news is there are more options than ever. Airlines connect dozens of US cities to Australia’s main gateways — Sydney, Melbourne, Brisbane and Perth — with a range of stopovers in the Pacific, Asia and beyond. The bad news is that some routes are dramatically more comfortable than others, and the price gap between a brilliant flight and a nightmare one isn’t as wide as you’d hope.
📋 TL;DR — the quick version

- 🇦🇺 Qantas is the most beloved option on this route with strong service and the most direct flying.
- 🌐 Air New Zealand via Auckland and Hawaiian Airlines via Honolulu offer excellent stopovers.
- ✈️ Non-stop options exist from LA and Dallas Fort Worth on Qantas.
✈️ Who flies from the USA to Australia?
Qantas is the dominant carrier on this route and operates the most direct services. From Los Angeles, Qantas flies non-stop to Sydney, Melbourne and Brisbane. From Dallas Fort Worth, it operates a non-stop service to Sydney — one of the longest commercial routes in the world at around 17 hours. The airline also partners with American Airlines to offer connecting itineraries from East Coast cities.
United Airlines flies from Los Angeles, San Francisco and Houston to Sydney and Melbourne, often in partnership with Air New Zealand. The product has improved significantly in recent years, particularly on Polaris business class.
Air New Zealand routes via Auckland from Los Angeles, San Francisco and Houston. The Auckland stopover is genuinely enjoyable — even a few hours gives you a taste of New Zealand. The airline has a brilliant reputation for service and innovation. The Skycouch in economy (three seats that convert to a flat surface) is clever for couples.
Hawaiian Airlines connects Los Angeles and other US cities via Honolulu to Sydney. Honolulu is one of the world’s great stopover cities — even a day there adds a beach holiday to your itinerary.
American Airlines codeshares with Qantas on many routes, so you can book through AA but end up on a Qantas plane — usually a very good outcome.

🗺️ Routing options: which way should you fly?
Via the Pacific (Los Angeles or San Francisco): This is the most direct routing for most US travellers. LA to Sydney is around 15 hours non-stop, making it one of the most manageable ultra-long-haul options. If you’re on the West Coast, this is clearly the right choice.
Via Dallas Fort Worth (DFW) to Sydney: Qantas operates this route and it’s genuinely impressive — one of the world’s longest commercial flights. It’s convenient if you’re in the southern or central US and want to avoid backtracking to LA.
Via Auckland (Air New Zealand): A fantastic option if you want to make the journey feel more like an adventure. Auckland is a beautiful city and even a short stopover is worthwhile. Flights from LA or San Francisco are frequent.
Via Honolulu (Hawaiian Airlines): Honolulu is one of the most enjoyable transit points on the planet. Book a longer layover intentionally if you’ve never been to Hawaii — it adds minimal cost and massive experience value.
Via Asia (Middle Eastern airlines connecting through hubs): Some travellers from the US East Coast find it cheaper to fly eastbound — over the Atlantic, through Dubai or Doha, and on to Australia. This adds significant total journey time but can produce impressive deals, especially if you fancy a Middle East stopover.
💺 Economy class: who does it best?
Air New Zealand leads the pack for economy innovation. The Skycouch (available on international Boeing 777 flights) is a genuine game-changer for couples — three seats fold flat to create a surface that makes long-haul much more comfortable. Standard economy seats are also among the better ones in the sky.
Qantas economy has improved substantially in recent years. Seat pitch is decent, the entertainment system has good content, and the food — especially the Australian-inspired meals — is above average. The crew are warm and professional, which makes a genuine difference on a 15-hour flight.
United economy is functional but unremarkable. The newer Polaris cabin is excellent, but economy is similar to most US carriers — fine for the price, not a memorable experience. Seat pitch on transpacific 787s is reasonable.
Hawaiian Airlines economy is pleasant and relaxed, with a strong Hawaiian cultural touch — island-inspired food and a genuinely warm atmosphere. It’s one of the more enjoyable economy products on any Pacific routing.
🌟 Business and premium class: the best seats across the Pacific
Qantas Business on the A380 (used on the LA–Sydney and DFW–Sydney routes) is excellent. Fully flat beds, direct aisle access, a strong menu and characteristically warm Australian service. The Qantas First Class Lounge in Los Angeles is also a premium pre-flight experience.
Air New Zealand Business Premier is outstanding. The seat design is genuinely creative — a fully flat, door-adjacent pod with great privacy. The New Zealand food and wine offering is superb: think fine lamb, Marlborough Sauvignon Blanc and pavlova. Easily one of the best business class products crossing the Pacific.
United Polaris has closed the gap significantly and is now a strong business class product. The bedding (designed by Saks Fifth Avenue) is excellent, the food has improved dramatically, and the Polaris lounges at SFO and LAX are very good.

💡 Insider tips for booking from the USA
Fly from Los Angeles if at all possible. Even if you’re on the East Coast, positioning yourself in LA for the transpacific leg is usually more comfortable and cost-effective. You get non-stop options and avoid the gruelling 20+ hour total journey time from New York via Asia.
Look for Qantas sales in January. Qantas regularly runs significant sales in late January and early February, aimed at Australian expats returning home after Christmas. Economy return fares from LA to Sydney for under $800 USD are possible during these windows.
Consider the Air New Zealand fare bundles. Air New Zealand’s fare structure is clear and the add-on pricing is transparent. The Skycouch add-on for couples is typically $400–$600 per person extra and is genuinely worth it on a 13-hour LA to Auckland leg.
Use Google Flights’ price calendar. The flexible date view on Google Flights is the single most useful tool for finding cheap transpacific fares. Being flexible by even 2–3 days can save hundreds of dollars.
Join Qantas Frequent Flyer. Even if you’re not Australian, the Qantas Frequent Flyer programme is excellent for accumulating and redeeming points on this route. The programme partners with American Airlines, Cathay Pacific, British Airways and many others.
⏰ How long does the journey actually take?
From Los Angeles, non-stop to Sydney is approximately 15 hours. Add domestic connection time plus the 5–6 hour flight from an East Coast city to LA, and you’re looking at 22–24 hours door to door from New York. From Dallas Fort Worth direct to Sydney with Qantas is around 17 hours in the air.
There’s also a time zone shock to prepare for. Australia is 15–19 hours ahead of the US, depending on the time of year and your specific US city. The jet lag is significant — plan for 3–5 days of adjustment and give yourself a buffer before any important commitments on arrival.
🏆 Which airline should you choose from the USA?
For pure directness and Australian character: Qantas. The LA or DFW direct services are the most comfortable routing and the airline just feels right heading to Australia.
For best economy innovation: Air New Zealand. The Skycouch alone makes it worth considering for couples or anyone who values sleep.
For best stopover potential: Hawaiian Airlines via Honolulu or Air New Zealand via Auckland. Both add an incredible destination to your itinerary at minimal extra cost.
For best business class value: Watch for Qantas and Air New Zealand business class sales — both offer genuinely premium products at prices that are reasonable for this distance. Once you land, check our guide to the best time to visit Australia to plan the rest of your trip.
