If you’re dreaming of a holiday in 2026, whether it’s a quick jaunt to see the grandkids, a long-awaited overseas adventure, or a cheeky escape to somewhere warm, one thing’s for sure: nobody wants to pay more than they have to for flights. But from last-minute price jumps to confusing fare comparisons, booking a flight can quickly become frustrating.
So, how do you actually nab the best deal? According to experts, travellers who understand these patterns and use these strategies can still find affordable flights, even during peak periods.
Forget the old wives’ tales about booking on a Tuesday for cheaper flights! Let’s dive into the real, up-to-date strategies for affordable air travel, with plenty of practical advice you might not have heard before.
Why Do Flight Prices Jump Around So Much?
If you’ve ever checked a flight one day and found it $100 more (or less!) the next, you’re not alone. Airfares are famously fickle, and there’s a good reason for it. Airlines use complex algorithms that factor in demand, competition, fuel prices, and even the time of year.
Head of Expedia Group brands public relations Melanie Fish had this to say: ‘Flight prices are influenced by demand, competition, fuel costs, and seasonal trends. If airlines notice they aren’t selling as many seats as expected, or low-cost carriers are coming in at a much lower price, they may adjust.’
When Should You Book?
Travel experts have moved on from the ‘book on a Tuesday’ myth. Instead, they recommend focusing on the booking window, which is the sweet spot when fares are most likely to be at their lowest. Here’s a handy guide:
- Domestic flights (off-season flights): Book 1–3 months in advance.
- Domestic flights (peak times like school or summer holidays): Book 3–7 months ahead.
- International flights (off-peak): Book 2–8 months in advance.
- International flights (peak times): Book 3.5–9 months ahead.
If you’re planning a big trip, set a reminder and start looking early. According to Expedia’s latest data, booking 1–3 months ahead for domestic flights can save you up to 25 per cent compared to last-minute bookings. For international trips, Google’s research suggests the lowest prices are usually found 49 days (about 7 weeks) before departure, but this can vary by destination.
Ms Fish shared: ‘Keep in mind that the beginning of the year is a popular time for people to start planning vacations, so if you’re headed to Paris in June, for example, you’ll want to book your flights and accommodations sooner rather than later.’
Set Alerts and Let Technology Do the Work
Don’t fancy checking prices every day? Good news! There are plenty of tools that can do the hard work for you. Google Flights, Skyscanner, and Kayak all let you set price alerts for your chosen route and dates. You’ll get an email if the price drops, so you can pounce on a deal without constantly refreshing your browser.
‘Deal alert websites such as Thrifty [Traveller], Going, and Dollar Flight Club are all great ways to set your search on autopilot,’ says Julian Kheel, founder and CEO of Points Path.
He continued: ‘Most major U.S. airlines made the vast majority of their airfares easy to rebook without paying a penalty—one exception is basic economy fares. So if you see a flight that seems reasonably priced, you should book it, but then continue to monitor it even after you book. If the price drops, it costs nothing to cancel and rebook at the lower price and get a flight credit for the difference.’
Is There a Best Day to Book or Fly?
The old ‘book on a Tuesday’ rule is, sadly, outdated. Airlines now update their prices in real time, not just once a week.
However, there are better days to fly if you want to save money. Generally, Tuesdays, Wednesdays, and Saturdays are less popular travel days, so you’ll often find cheaper fares and emptier planes. Sundays and Fridays tend to be the most expensive, as that’s when most people want to travel.
Timing Your Trip: The Cheapest Months and Days
If you’re flexible with your travel dates, you can save a bundle. January and February are usually the cheapest months to fly, as demand drops after the Christmas rush. For international trips, late August is a sweet spot because school holidays are winding down, crowds are thinning, and airlines are keen to fill seats.
Expedia’s data even pinpoints the cheapest days: for domestic flights, August 19 and 25 are top picks, while for international journeys, aim for mid-to-late August.
Booking Too Early And Too Late
While it’s tempting to hold out for a last-minute deal, this is a risky game, especially for international flights. Airlines know that business travellers and those with urgent needs will pay top dollar, so prices often soar as the departure date approaches. If you’re travelling overseas, book as early as possible within the recommended window.
But it’s also possible to book too early. Airlines don’t always release their best prices a year in advance. Instead, they start with higher fares and drop them as the date approaches and they get a sense of demand. That’s why the Goldilocks Window is so important. Book too soon, and you might pay more than you need to.
Can AI Help You Find Cheaper Flights?
Artificial intelligence is making waves in travel, too. Google’s new AI-powered ‘Flight Deals’ tool can help you find cheap fares, especially if you’re flexible about where and when you go. Just tell the AI your travel dreams, and it’ll suggest destinations and deals.
But don’t expect miracles because AI is still learning the ropes. Think of it as a helpful assistant, instead of a miracle worker.
Flexibility Is Your Secret Weapon
The more flexible you are, the more you’ll save. If you’re happy to travel at odd hours, take a longer layover, or visit less-popular destinations, you’ll find the best bargains. And remember: a cheap flight isn’t always a good deal if it means three stopovers and a 2 am arrival!
‘The best tried and true method of getting low airfares is to travel to destinations at lower demand times when fewer people are clamouring to go to the same place,’ Kheel shared.
Key Takeaways
- Flight prices are highly volatile and influenced by factors like demand, competition, fuel costs and seasonal trends, so there’s no single day that guarantees the cheapest fare.
- Booking within recommended timeframes can help you save, with one to three months ahead best for domestic flights and a bit earlier for international, but last-minute fares are usually expensive.
- Setting up price alerts with tools like Google Flights and deal websites can help you monitor fare drops, and many airlines now allow you to rebook at a lower price without penalties if you find a cheaper fare after booking.
- Flexibility is key! Travelling on less popular days (like Tuesdays, Wednesdays and Saturdays), during low-demand months (like late August, January or February), or to less-visited destinations often leads to better deals.
