How to Find Cheap Flights: 12 Proven Tips That Actually Work
Save on airfare with flexible dates, fare alerts, nearby airports, the right booking window and smart tricks for comparing total ticket prices.
- Be flexible with dates and airports — it is the biggest money saver.
- Set price alerts and compare several search engines.
- Always compare the total price including bags and seat fees.
- Book roughly 1–3 months ahead for domestic and 2–6 months for international.
Airfare is often the largest single expense of a trip. You do not need secret hacks to save — just a consistent method. These 12 tips are the ones that make the biggest difference.
1. Be flexible with your dates
Moving your departure by one or two days can change the price significantly. Use the calendar or “flexible dates” view on flight search engines to see the cheapest days of the month at a glance.
2. Fly midweek
Tuesday, Wednesday and Saturday departures are often cheaper than Friday and Sunday, which are popular with business and weekend travelers.
3. Compare nearby airports
Large cities frequently have more than one airport, and secondary airports may be served by low-cost carriers. Include ground transport costs and time in your comparison.
4. Set price alerts
Instead of checking every day, create alerts on two or three search engines for your route. You will be notified when the price drops.
5. Book in the right window
Very early and very last-minute bookings are rarely the best deal. As a general guide, aim for about 1–3 months ahead for domestic flights and 2–6 months for international flights, earlier for holidays and peak summer.
6. Compare more than one search engine
Different sites show different airlines and booking agents. Check at least two metasearch engines, then look at the airline’s own website before you pay.
7. Compare the total price, not the headline fare
Low fares can hide fees for carry-on bags, checked bags, seat selection and even printing a boarding pass. Add everything you will need before comparing.
8. Consider one-way and mixed tickets
Sometimes two one-way tickets on different airlines cost less than a round trip. Be aware that separate tickets are not protected if one flight is delayed and you miss the next.
9. Try open-jaw routes
Flying into one city and out of another can save money and backtracking on multi-city trips.
10. Use points and miles wisely
Airline and credit card reward programs can cover a big part of a ticket. Compare the cash price to the points needed to make sure you are getting good value.
11. Travel light
Flying with only a personal item or carry-on unlocks the cheapest fare classes. See our carry-on packing checklist.
12. Know your rights
Many jurisdictions require refunds or compensation for long delays and cancellations in certain situations. Check the rules that apply to your route and airline, and keep receipts for any extra costs.
Quick comparison: budget vs. traditional airline
| Item | Budget airline | Traditional airline |
|---|---|---|
| Base fare | Usually lower | Usually higher |
| Carry-on bag | Often extra | Often included |
| Checked bag | Extra | Depends on fare |
| Seat selection | Extra | Often included or cheaper |
| Flexibility | Limited | More options |
Bottom line: flexibility plus alerts beats any trick. Once your flight is booked, continue with our step-by-step trip planning checklist.
Frequently asked questions
What is the cheapest day to fly?
Midweek flights, especially on Tuesdays and Wednesdays, are often cheaper than Fridays and Sundays because demand is lower. Use a flexible-date calendar to confirm for your route.
Does searching in incognito mode make flights cheaper?
There is little evidence that airlines raise prices because of your cookies. Prices change because of demand and seat availability, so comparing sites and setting alerts matters more.
Are budget airlines always cheaper?
Not always. Once you add checked bags, carry-on fees and seat selection, a traditional airline can cost the same or less. Compare the total cost of your trip.
