How to Find Cheap International Flights: 7 Steps That Work

The way to find cheap international flights is to search wide before you search narrow, compare the full price including bags, and book when a fare is clearly below the usual price for that route. Doing it in this order beats refreshing the same search every day.

International fares move more than most people expect, and the same trip can cost very different amounts depending on the airport you leave from, the day you fly and the baggage you need. The steps below work from any departure airport.

Why international fares feel so unpredictable

Long-haul and cross-border fares are priced by many airlines at once, each with its own fare buckets, and they change as seats sell. In a recent r/travel thread, a traveler pricing a trip from Portland to Edinburgh found little under $1,300 without very long layovers and asked whether they were simply looking at the wrong time. The replies were a mix of fuel costs, school-holiday demand and flexibility on dates. That is a fair summary: price depends on timing, route and what you are willing to trade.

You cannot control fuel prices, but you can control how wide you search and how patient you are.

Step 1: Start with "anywhere" instead of a destination

If the destination is flexible, let the price choose it. Several commenters in the same community recommend the map or "Explore" view in tools such as Google Flights, Skyscanner and Kayak: enter your departure airport, leave the destination open and sort by price. A commenter in r/travel put it in four words: "Google Flights - and then hit Explore".

Use this to find a shortlist of three or four places, not a final answer.

Step 2: Check nearby departure airports

A different departure airport can change the price a lot. The same thread suggests that flying out of a larger hub nearby can save real money, even after the cost of getting there. Compare airports within a few hours of home, and add the ground transport cost before you decide.

Large hubs often have more airlines competing on the same route. You can see today's lowest fares from airports we track on pages like Madrid. As of 4 November 2026, the lowest fare shown there is 31 EUR to Marrakesh, with a 30-day low of 29 EUR. Fares like this change quickly and are not a promise, so treat them as a sense of scale.

Step 3: Be flexible by a few days, not just a few hours

Search a full month, or a flexible-date grid, rather than one pair of dates. Midweek departures are often cheaper than Friday and Sunday, but this varies by route, so check instead of assuming. Moving a trip by two or three days is often worth more than any trick.

Step 4: Compare the full price, not the headline price

A low base fare can grow once you add a checked bag, a seat and a meal. This is the most common surprise on international trips with budget carriers.

What to add	Why it matters
Checked bag	Often not included in the lowest fare
Seat selection	Sometimes charged even for a basic seat
Ground transport	Budget airlines may use a secondary airport
Connection risk	Separate tickets are not protected if the first flight is late

Our comparison of low-cost and full-service airlines shows when the cheaper ticket really is cheaper once you add what you need.

Step 5: Look at the airlines' own sites too

Not every airline appears in every search tool. One commenter notes that some budget carriers do not list their flights on the big aggregators, so you have to visit their websites. After you find a route that looks good, check which airlines fly it and look at their pages before you book. Our guide to booking through an airline site or a booking site explains the trade-offs.

Step 6: Set up price alerts and wait for a clear dip

If your dates are not fixed, searching every day is tiring and easy to get wrong. A price alert does the watching for you. Google Flights can track a route and email you when the price changes, including an "any dates" option, as described in Google's help page.

Cheap Flights Alert works from the other direction. It is a free service that watches prices from the departure airport you choose and messages you when a fare is clearly cheaper than usual. Every fare is compared with the recent prices from the same airport, and only deals with a score of 80% or more are sent. You can get them on WhatsApp, Telegram or email. Sign up for alerts and pick your home airport. It does not book flights: it sends the deal and a link, and you book with the airline or booking site.

It is also honest to say what it is not. It works from a list of major airports in the United States and Europe, and it does not predict whether a price will rise or fall. If you have a fixed route and fixed dates, a route search in Google Flights is a better fit.

Step 7: Decide in advance what a good price is

The hardest part of booking is knowing when to stop looking. Before you start, write down a price you would be happy with for your route. Then use two or three searches over a week or two to see where the usual range sits. If you see a fare at or below your number, with a bag included and a reasonable schedule, book it. Waiting for an extra 20 EUR saving often costs more in stress than it saves. Our article on how to tell a real deal from a normal price goes deeper on this.

A simple routine you can reuse

1. Open an "anywhere" search from your home airport and note three cheap destinations.
2. Compare one or two nearby airports.
3. Search a whole month, then narrow to the cheapest days.
4. Add bags and seats to each result and compare the total.
5. Check the airline's own site for the best option.
6. Set an alert for the route and for your home airport.
7. Book when the full price meets the number you decided on.

If you are heading to Europe from North America, the step-by-step guide to cheap flights to Europe applies the same ideas to one region.

Where this method falls short

None of this guarantees a low price. During busy holiday periods, demand can keep fares high no matter how well you search, and a last-minute trip leaves little room to wait. Alerts only help if a good fare appears while you are watching. When your dates and route are fixed, spend your time on the full-price comparison in step 4 instead.
