Booking flights using savvy insights can deliver serious savings. Expedia’s 2025 Air Hacks Report—drawing from billions of price points across the globe—reveals smart strategies for Australians to travel more affordably without compromising comfort or timing.
When to Book for Maximum Savings
- Book domestic flights about six months ahead for the best deals—savings can reach 20–36% compared to last-minute bookings. This recommendation is based on an analysis of booking patterns from ARC and OAG databases.
- International flight bookings hit peak value 2–3 months before departure, where fares can be up to 17% cheaper than those booked earlier than five months ahead.
Days to Book and Days to Fly
- Booking on a Sunday offers the best bargains—Australians can expect to save up to 20% for domestic tickets and up to 17% for international flights versus Fridays or Mondays.
- Departing midweek is cheaper: Thursdays for international trips and Saturdays for domestic flights can save travellers up to 27% compared to busier days like Monday or Sunday.
Best Months to Travel
- January—despite being a high holiday season—is identified as the cheapest month to fly in both economy and premium cabins (savings of 11%).
- In contrast, September and October register higher fares, particularly in premium fare classes.
- February and March emerge as the least disrupted travel months, featuring the lowest cancellation rates of the year and calmer airport experiences.
Expedia’s headline travel hack for Australians is this:
“Book on Sunday, fly midweek, travel in January or August, and schedule far ahead domestically or close in for international!”
Using Expedia’s own Flight Deals tool and Price Tracker in their app gives users real-time updates when fares drop, with alerts triggered when prices fall 20% below the typical value.
Putting It All Together: Sample Scenarios
Scenario 1: A Domestic Trip
You’re planning a family holiday from Sydney to Adelaide in July:
- Book on a Sunday six months in advance
- Depart on a Saturday for up to 27% off peak fare
- Expect better reliability and fewer delays if travelling in February or March
Scenario 2: International Travel to Europe
You hope to fly from Melbourne to Spain next year:
- Book during the 2–3 month lead time for savings up to 17%
- Travel midweek—preferably Thursday—for added fare discounts
- January or August offers economy rates up to 11% cheaper than September fares.
Why This Hack Works
- Ticket pricing is data-driven, following supply tiers and demand surges. Booking far in advance can lock in early high fares, while booking too close to departure may leave you with last-tier pricing.
- Airlines adjust their capacity and offer midweek departures—such as Thursday and Saturday—to avoid premium weekend demand.
- Sunday bookings align with airline fare updates and lead times, making them more likely to hit lower fare classes.
What to Watch Out For
- Don’t overbook your flexibility too far ahead—if your travel dates are firm, take advantage of early locks.
- Price tracking tools like Expedia’s Price Tracker or Skyscanner alerts can help, but keep in mind that fares can shift day to day.
- Red-eye vs. daytime departures may affect cancellation risk. Morning flights (9 a.m.– 3 p.m.) are statistically less likely to be cancelled than evening ones.
Final Thoughts
Expedia’s 2025 Air Hacks Report offers valuable, data-backed insights for Australians looking to save on airfare. It debunks the myth that longer lead times always equate to lower fares, and instead promotes strategic booking windows and travel days.
Whether you're flying across the Nullarbor or halfway around the world, these timing tips—combined with savvy use of price tracking tools—can help trim hundreds off your ticket costs while avoiding crowds and disruptions.
And once you land, especially in cities like Melbourne, consider fully furnished apartments for a more comfortable and flexible stay. Providers such as Corporate Keys offer long and short-term accommodation that blends the comfort of home with the convenience of hotel living—perfect for travellers who want more than just a place to sleep.
