You’re staring at a screen in the middle of a Chicago winter. It’s gray. It’s -5 degrees. The idea of landing in Melbourne, where the coffee is actually a religion and the "winter" feels like a mild O'Hare spring, is more than a dream. It’s a survival tactic. But then you see the price tag. Your stomach drops.
Planning for airfare to Melbourne from Chicago is notoriously tricky. This isn't a quick hop to London or a weekend in Tulum. You are effectively traveling to the other side of the planet. Roughly 9,700 miles. That is nearly half the circumference of the Earth.
If you just hop on a search engine and click the first "deal" you see, you're probably overpaying by $400 or more. Honestly, I’ve seen people drop $2,200 on a flight that should have cost $1,300 just because they didn't understand how the transpacific pricing cycles actually work.
The Reality of the ORD to MEL Route
First things first: you aren't flying direct. Nobody is. As of early 2026, there are no nonstop flights from Chicago O'Hare (ORD) to Melbourne (MEL). You’re going to have a layover. Somewhere. Usually, that means Los Angeles (LAX), San Francisco (SFO), or Dallas (DFW).
If you’re feeling adventurous, you might head West through Tokyo (NRT) or even East through Doha (DOH) on Qatar Airways. But those "around the world" routes add massive hours to an already grueling journey. A standard one-stop flight through the West Coast will take you about 22 to 24 hours. If you go through the Middle East, you’re looking at 30+ hours easily.

Why does this matter for your wallet? Because the layover city often dictates the price more than the airline itself.
Why July is Secretly Your Best Friend
Most people want to visit Melbourne during the Australian summer (December to February). That is the peak. Prices for airfare to Melbourne from Chicago during these months regularly spike 20% above the annual average.
But here is the kicker: Melbourne’s "winter" in July is actually great for budget travelers. It’s not "Chicago cold." It’s "light jacket and a scarf" cold. Recent data shows that July is consistently the cheapest month to fly this route. You can often snag round-trip tickets for around $1,280. Compare that to the $1,900+ you’ll pay in late January when the Australian Open is in full swing and every seat is spoken for.
If you can't do July, aim for May. It’s the sweet spot. The weather is crisp, the crowds are gone, and the airlines are desperate to fill seats before the mid-year slump.
The Airline Shell Game: Who to Trust
You have choices. A lot of them. But not all 20-hour flights are created equal.
- United Airlines: They are the heavy hitters on this route. They run a ton of connections through SFO and LAX. If you’re a MileagePlus devotee, this is your path. Their Polaris business class is genuinely solid now, but economy is... well, it’s economy.
- Qantas: Australia’s flagship. They often partner with American Airlines. You’ll likely fly AA to the coast and then the "Flying Kangaroo" across the pond. Their service is legendary, and honestly, their wine list in premium cabins is a great introduction to Aussie culture.
- Air Canada: Don't sleep on the Great White North. Sometimes flying ORD to Vancouver (YVR) or Toronto (YYZ) and then down to Melbourne is significantly cheaper. I’ve seen some "hacker fares" using Air Canada and Virgin Australia that beat the US majors by hundreds.
- The Asian Carriers: JAL and ANA (through Tokyo) or Cathay Pacific (through Hong Kong). These are for the comfort seekers. The service is often levels above US domestic carriers. Just be prepared for a longer total travel time.
The "Two-Ticket" Strategy
Sometimes, the best airfare to Melbourne from Chicago isn't a single booking. Check the price of a flight from ORD to LAX separately from a flight from LAX to MEL. Occasionally, a budget carrier like Jetstar or a deal on Qantas out of the West Coast is so cheap that it justifies buying a separate domestic leg on Southwest or United.
Just a warning: if you do this, give yourself a massive layover. Like, six hours. If your Chicago flight is delayed and you miss your separate international booking, the airline doesn't owe you anything. You're stranded.
What No One Tells You About the "Cheap" Fares
You’ll see numbers like $927 or $1,050 pop up on discount sites. Be careful. In 2026, "Basic Economy" has gone global. Those bottom-dollar prices often don’t include a checked bag. On a 24-hour trip, you probably need a suitcase. Once you add the $150 round-trip bag fee, that "deal" is just a standard fare in disguise.

Also, check the layover times. A 45-minute layover in LAX is a nightmare. You have to change terminals, often going from the domestic gates to the Tom Bradley International Terminal. It’s a trek. If you miss that connection, you might be waiting 24 hours for the next flight to Melbourne.
Aim for a 2-to-3-hour window. It’s enough time to grab a burger, stretch your legs, and not sprint through the airport like a maniac.
Visas and the "Fine Print"
You cannot just show up in Melbourne with a US passport and a smile. You need an ETA (Electronic Travel Authority). It’s basically a digital visa. It’s easy to get through the official Australian ETA app, but if you forget it, you won't even be allowed to board your flight at O'Hare.
It usually costs around $20 AUD. Don’t use third-party websites that charge $100 for "processing." Use the official government app.
Actionable Steps for Your Booking
Stop just "browsing" and start executing. Here is exactly how to handle your search for airfare to Melbourne from Chicago right now:
- Set a Google Flights alert today. Don't wait. Use the "Track Prices" toggle for your specific dates. You want to see the trend, not just a snapshot.
- Book 2-3 months out. For international transpacific hauls, the "sweet spot" hasn't changed. Booking six months early is often as expensive as booking two weeks late.
- Check O'Hare (ORD) AND Midway (MDW). While ORD has more options, Delta occasionally runs aggressive deals out of Midway that connect through Atlanta or Minneapolis before heading to the coast.
- Verify the airport code. Make sure you are flying into MEL (Tullamarine). There is another airport called Avalon (AVV). It’s much further from the city. If the flight is $50 cheaper but the Uber to your hotel is $120, you didn't save money.
- Join the frequent flyer program BEFORE you buy. Even a single round-trip to Australia will earn you enough points for a free domestic flight within the US later. Don't leave those miles on the table.
Melbourne is waiting. The Great Ocean Road, the street art in the laneways, and the best flat white you've ever had are all on the other side of a very long flight. Just make sure you aren't paying for the pilot's retirement when you book your seat.
