Airfares are set by complex pricing systems that change prices constantly based on demand, season and how many seats are left. There’s no single magic trick, and many popular “hacks” don’t hold up. But a handful of habits reliably save money. Here are 10 that still work, plus a few myths you can stop worrying about.
1. Be flexible on dates
Flexibility is the biggest saving of all. Moving a trip by a day or two, or flying midweek instead of Friday or Sunday, can change the price significantly. Use the calendar or price-graph views on search sites to see a whole month at a glance.
2. Use fare-comparison tools and price alerts
Google Flights, Skyscanner, Kayak and Momondo compare many airlines at once. Set a price alert for your route and dates, and you’ll get an email when the fare drops, instead of checking every day.
3. Book in the “sweet spot”
Prices often rise sharply in the final weeks before departure. As a rough guide from fare-tracking studies:
| Trip type | Typical good booking window |
|---|---|
| Short-haul / domestic | 1–3 months ahead |
| Long-haul / international | 2–6 months ahead |
| Peak season (summer, holidays) | Earlier, often 4–8 months ahead |
These are averages, not guarantees, which is why price alerts are so useful.
4. Check nearby airports
Many cities have several airports, and budget airlines often use smaller secondary ones. Search “all airports” for your city, or check airports within a couple of hours’ travel. Factor in the cost and time of getting there.
5. Try “everywhere” or map searches
If you’re flexible about where you go, explore tools let you enter your home airport and see the cheapest destinations for your dates.
6. Compare the total price, not the headline fare
A cheap budget fare can end up costing more than a full-service ticket once you add bags, seat selection and fees. Check what’s included before you compare:
- Cabin bag and checked bag allowances
- Seat selection, meals and payment fees
- Airport transfer costs
7. Consider one-way and mixed airlines
Two one-way tickets on different airlines are sometimes cheaper than a return on one. The trade-off: if one flight is delayed or cancelled, the other airline has no obligation to help, so leave generous connection times on separate tickets.
8. Travel off-season or shoulder season
Flights around school holidays and major festivals are always pricier. Spring and autumn “shoulder seasons” often offer good weather, smaller crowds and lower fares.
9. Book directly when it’s close
Once you’ve found a fare, check the airline’s own website. If the price is similar, booking direct usually makes changes, refunds and disruption much easier to handle.
10. Use points and rules in your favour
Join the free frequent-flyer scheme of airlines you use often. If you fly to or from the US, the Department of Transportation requires airlines to let you cancel within 24 hours for a full refund, or hold a fare, for most tickets booked at least seven days before departure. That gives you a short window to keep watching prices.
Myths you can ignore
- “Always book on a Tuesday.” Large studies of fare data show little reliable difference by day of booking. The day you fly matters more.
- “Prices rise if you search repeatedly.” There’s little evidence of this. Prices change because demand changes.
- “Last-minute deals are the cheapest.” For most routes, fares rise close to departure.
