How to Find Cheap Long-Haul Flights: 17 Proven Tips
Finding an affordable long-haul ticket can feel like a lottery. One passenger may pay €450 for a return journey while the person sitting beside them paid more than €900 for almost exactly the same experience.
But airfare is not entirely random. Prices change according to demand, competition, travel dates, available seats, departure airports and the way airlines manage their fares. Travellers who understand these factors have a much better chance of finding a genuinely good deal.
This guide explains how to find cheap long-haul flights using practical strategies that work across international routes. It will also help you recognise misleading bargains, avoid unnecessary fees and decide when it is better to book rather than continue waiting for a lower price.
How to Find Cheap Long-Haul Flights: The Quick Answer
To find cheap long-haul flights, compare several departure dates and airports, create fare alerts, search early and remain flexible about routes and airlines. Compare the total price—including baggage, seat selection and payment fees—before booking.
There is no single day or secret website that always produces the cheapest fare. The strongest results usually come from combining several methods and acting quickly when a reasonable price appears.

1. Start Searching Early—but Not Too Early
Long-haul flights usually become available around 10 to 12 months before departure, but the first price displayed is not necessarily the lowest. Airlines may initially release seats at cautious prices and adjust them as demand becomes clearer.
For most international journeys, begin monitoring prices several months before travelling. This gives you time to understand the normal fare for the route and recognise a genuine reduction.
Searching early is particularly important when travelling during school holidays, Christmas, Easter or major international events. Waiting for a last-minute bargain during these periods can be risky because the cheapest fare categories may sell out first.
2. Compare Flexible Travel Dates
Changing your departure by just one or two days can sometimes reduce the fare considerably. Flights on Fridays, Sundays and immediately before public holidays are often more expensive because demand is higher.
Use a flexible-date calendar instead of checking only one specific day. Compare prices across an entire week or month whenever your circumstances allow.
Midweek departures are sometimes cheaper, but this is not a universal rule. The cheapest day depends on the route, season and passenger demand. Let the actual fare calendar guide your decision rather than relying on a fixed “best day to fly.”
3. Compare Nearby Departure Airports
Your nearest airport may be convenient, but it may not offer the lowest long-haul fare. Larger airports usually have more airline competition, while some smaller airports attract low-cost feeder services that can make an alternative journey worthwhile.
For example, a traveller in Ireland might compare departures from Dublin, Belfast, Cork, Manchester or London. A passenger living near a European border may find an even larger difference by checking airports in a neighbouring country.
However, calculate the complete cost of reaching the alternative airport. Include transport, parking, hotels, meals and the additional time involved. Saving €100 on the flight is not a true saving if positioning costs add €150.
4. Set Fare Alerts Instead of Searching Constantly
Fare alerts monitor a route and notify you when the price changes. They are useful because long-haul fares can rise or fall several times while you are considering a journey.
Create alerts for more than one set of dates and, when practical, more than one departure airport. This gives you a broader view of the market and makes it easier to identify an unusually good price.
An alert is only a signal—not proof that you must book immediately. Before purchasing, check the fare conditions, baggage allowance, connection time and final checkout price.
5. Compare Prices Across More Than One Search Tool
No flight comparison service displays every airline or every possible fare. Search results may also differ because platforms receive their information from different booking partners.
Compare the same journey across at least two reliable search tools, and then check the operating airline’s website. Pay attention to whether the quoted price includes checked baggage, cabin baggage, seat selection and other services you may need.
A fare that initially appears cheaper can become more expensive after these extras are added. Always compare the final price rather than the first number displayed in the search results.

6. Search One Passenger Before Searching for a Group
Airline booking systems divide seats into different fare categories. If only one seat remains in the cheapest category and you search for four passengers together, the system may quote all four tickets at the next available price.
Begin by searching for one passenger to see the lowest available fare. Then repeat the search for the full group.
If the prices differ substantially, you could consider making separate bookings. However, passengers on separate reservations may need individual assistance if a flight is cancelled or changed. Families travelling with children should be particularly careful about splitting reservations.
7. Consider One-Stop Flights
A direct flight offers convenience, but a journey with one well-planned connection can cost considerably less. Connecting routes also allow you to compare more airlines and departure times.
The cheapest itinerary is not always the best value. Avoid extremely short connections that could be difficult during delays, immigration or terminal changes. Very long overnight connections may also require food, airport accommodation or a hotel.
Compare the saving with the additional journey time and inconvenience. Paying slightly more for a sensible connection can be better than choosing the cheapest possible itinerary.
8. Check Different Airline Combinations
A return ticket does not always need to use the same airline in both directions. One carrier may offer the lowest outbound fare while another provides a better price or schedule for the return journey.
Search for a traditional return ticket, two separate one-way tickets and mixed-airline combinations. This is especially useful on routes served by several competing carriers.
Separate tickets can carry additional risk. If one booking is delayed and causes you to miss a flight on another reservation, the second airline may not be required to rebook you. Allow a generous connection or an overnight stay when combining unrelated tickets.
9. Compare the Total Cost of the Fare
A basic ticket may exclude checked baggage, seat selection, meals, changes and other services. Once these are added, a more expensive-looking fare may provide better overall value.
Before paying, make a list of what you genuinely need. Compare the final checkout price of each option using the same baggage and seat requirements.
This is especially important on long-haul journeys, where baggage and seat-selection charges can add a significant amount to the original fare. Never choose a flight based only on the headline price.

10. Travel Outside Peak Seasons
Airfares generally rise when large numbers of passengers want to travel at the same time. Christmas, Easter, school holidays and major sporting or cultural events can make long-haul tickets considerably more expensive.
If possible, travel during the shoulder season—the period between the busiest and quietest parts of the year. You may find lower fares while still enjoying reasonable weather and open attractions.
Check the destination’s climate, local holidays and event calendar before booking. A very cheap ticket may coincide with extreme weather, widespread closures or another factor that reduces the value of the trip.
11. Consider an Open-Jaw Itinerary
An open-jaw ticket allows you to fly into one city and return from another. For example, you could fly from Dublin to New York, travel overland and return from Boston to Dublin.
This can reduce unnecessary backtracking and may also produce a lower fare. It is particularly useful for travellers visiting several cities or travelling across a large country.
Use the multi-city search option to compare the open-jaw itinerary with a standard return ticket. Remember to include the cost of travelling between the two destination cities.
12. Look Beyond the Most Famous Airlines
Major international airlines are not always the cheapest option. A less familiar carrier or an airline based in your connecting country may offer a competitive fare and acceptable service.
Research the airline before booking. Check its baggage rules, connection arrangements, cabin product and the airport used for the transfer.
Price matters, but an extremely cheap fare should not automatically outweigh an unsuitable schedule, poor connection or restrictive ticket conditions.

13. Compare Flights in Both Directions
Sometimes reversing the order of a journey or beginning from another airport can reveal a different fare. This is particularly relevant when two countries have very different levels of airline competition or passenger demand.
If you regularly travel between two regions, compare return tickets originating from each side. However, you must begin the ticket at the departure point shown on the booking. Missing the first flight will normally cause the airline to cancel the remaining segments.
Never book a journey you do not genuinely intend to start as ticketed.
14. Use Points and Miles Strategically
Airline miles, credit-card points and loyalty rewards can reduce the cash cost of a long-haul journey. They can be particularly valuable when normal ticket prices are high.
Award seats may be limited, so flexibility is important. Compare several dates, routes and partner airlines instead of searching for only one flight.
Remember that a reward ticket may still include taxes, carrier charges and booking fees. Compare the complete cost with the price of an ordinary cash ticket before transferring or spending your points.
15. Consider a Positioning Flight
A positioning flight is a separate journey used to reach an airport offering a cheaper long-haul fare. For example, a traveller might fly from Dublin to another European city before beginning the main international ticket.
This strategy can produce savings, but it also creates risk when the flights are booked separately. If the positioning flight is delayed and you miss the long-haul departure, the long-haul airline may treat you as a no-show.
Allow a large safety margin—preferably an overnight stay—and include transport, accommodation, baggage and meals when calculating the real saving.
16. Treat Mistake Fares With Caution
Occasionally, an airline or booking platform displays an unusually low price because of a technical, currency or filing error. These offers are often described as mistake fares.
If you book one, avoid making expensive non-refundable arrangements immediately. The airline may honour the ticket, but there is also a possibility that it will be cancelled and refunded.
Wait until the ticket has been issued and the fare appears stable before building the rest of your trip around it. Even then, understand the cancellation and consumer-protection rules that apply to your booking.
17. Know When to Stop Waiting and Book
Trying to secure the absolute lowest possible fare can cause you to lose a perfectly good price. No traveller can reliably predict every future increase or reduction.
Decide in advance what you consider a reasonable price for the route. Once you find a suitable itinerary within your budget, with acceptable baggage rules and travel times, booking may be wiser than continuing to wait.
The best long-haul deal is not necessarily the cheapest ticket ever sold. It is a fare you can afford for a journey that meets your actual needs.

Frequently Asked Questions
What is the best time to book a long-haul flight?
There is no universal best booking day. Start monitoring fares several months before departure and book when you find an acceptable price. Peak-season journeys generally require earlier booking than quieter travel periods.
Are long-haul flights cheaper on Tuesdays?
Not consistently. Airlines change prices according to demand, remaining capacity and competition. A Tuesday may be cheaper on one route but more expensive on another. Comparing several dates is more reliable than following a fixed weekday rule.
Does searching repeatedly make flight prices increase?
There is no dependable evidence that repeatedly checking a flight automatically causes an airline to raise its price specifically for you. Prices can change quickly because fare categories sell out or availability is updated. Incognito mode may reduce stored browsing data, but it cannot guarantee a cheaper ticket.
Is it cheaper to book directly with the airline?
Not always. A comparison platform or travel agency may display a lower fare, while booking directly with the airline may make changes, refunds and disruption assistance easier. Compare both the price and the level of support before booking.
Are connecting long-haul flights always cheaper?
No. Connecting flights are often cheaper, but strong competition can make a direct flight equally affordable or occasionally less expensive. Compare the total journey time, connection risk and additional expenses—not just the ticket price.
Should I book a cheap flight immediately?
First check the dates, airports, baggage allowance, connection, fare conditions and final price. If the itinerary meets your needs and the price is reasonable for that route, delaying solely in the hope of a further reduction may cause you to lose it.
Final Thoughts
Learning how to find cheap long-haul flights is less about discovering a secret booking trick and more about making careful comparisons.
Flexible dates, alternative airports, fare alerts and sensible connections can all reduce the price. But every apparent bargain must be judged by its total cost, travel time, baggage allowance and booking conditions.
Do not allow the search for the lowest imaginable fare to lead you into an exhausting itinerary or a ticket that does not meet your needs. A genuinely good deal combines an affordable price with reasonable convenience and manageable risk.
Once you find that balance, book confidently make the long journey as comfortable as possible, and begin planning how to make the long journey as comfortable as possible.
