How to Find Cheap International Flights: 12 Expert Tips
International flights represent the biggest cost for most travellers. With the right strategies, you can cut your airfare significantly — sometimes by 50% or more. Here are 12 proven techniques our travel experts use every day.
Use price alert tools
Set up price alerts on Google Flights, Skyscanner and Kayak. When fares drop to your target price, you get an immediate notification.
Book on Tuesday or Wednesday
Airlines typically release deals on Monday nights, so Tuesday and Wednesday often see the lowest fares. Avoid booking on Fridays and Sundays when prices peak.
Be flexible on dates
Shifting your departure by even one or two days can save hundreds. Use flexible date search tools to see a calendar view of the cheapest days to fly.
Book 6–8 weeks in advance for domestic flights
The "Goldilocks zone" for domestic US flights is 1–3 months ahead. International flights are best booked 2–6 months before departure.
Consider nearby airports
Flying into a secondary airport near your destination can dramatically cut costs. New York has three major airports — Newark, JFK and LaGuardia — each with different price points.
Use incognito mode when searching
Airlines and booking sites track your searches and may raise prices when they detect repeat interest. Use a private browsing window to see unbiased pricing.
Mix and match airlines
Instead of booking a return with one carrier, compare separate one-way tickets on different airlines. This often results in significant savings, especially internationally.
Sign up for error fare newsletters
Mistake fares happen when airlines accidentally publish drastically reduced prices. Services like Secret Flying and Jack's Flight Club alert you immediately.
Consider budget carriers for short-haul routes
For flights under 3 hours, budget airlines like Spirit, Frontier or Southwest can be significantly cheaper — even accounting for bag fees.
Book connecting flights vs. direct
Direct flights command a premium. A connecting flight with a longer layover can cost 30–50% less, especially for transatlantic routes.
Use airline miles and points strategically
Credit card sign-up bonuses can earn enough points for a free business class ticket. Focus on one or two loyalty programmes for maximum value.
Travel during off-peak seasons
Travelling in January, February or November (outside school holidays) can halve your flight costs compared to peak summer or Christmas season.

Frequently Asked Questions
What is the cheapest day to fly internationally?
Tuesday and Wednesday are typically the cheapest days to fly. Departing mid-week avoids the business travel premium on Mondays and the leisure travel surge on Fridays and Sundays.
How far in advance should I book international flights?
For most international routes, booking 2–6 months in advance offers the best balance of availability and price. Trans-Pacific routes may benefit from earlier booking (4–8 months).
Is it cheaper to book flights directly with the airline?
Not always. Comparison sites often show you deals across multiple airlines simultaneously. However, booking directly with the airline can sometimes offer exclusive fares and better customer service.
Do flight prices go down last minute?
Occasionally, but this is a risky strategy. Last-minute prices are more often higher, especially for popular routes and dates. It works better for off-peak times and less popular routes.
What is an error fare?
An error fare is when an airline mistakenly publishes a price far below what it intended — sometimes 80–90% below normal fares. These are rare but very real. Services like Secret Flying and Dollar Flight Club track and publish them.
