How to Find Cheap Flights: A Step-by-Step Method

To find cheap flights, search with flexible dates and nearby airports, compare the total price including bags, and set up price tracking or deal alerts so you can book when a fare drops. The steps below turn that into a routine you can repeat for any trip.

1. Decide what you can change

Fares depend on three things: where you fly from, where you fly to, and when. The more of these you can move, the cheaper the result. Before you search, write down which of them are fixed and which are flexible:

• Dates: can you shift by a day or two, or travel mid-week?
• Destination: do you need one city, or just a region such as "somewhere warm in Europe"?
• Departure airport: is there another airport within a reasonable train or drive?

A fixed date and a fixed city is the hardest case. Even then, nearby airports and the luggage you take can change the price.

2. Use the flexible-date tools in a search engine

Google Flights, one of the most used flight search tools, has several features for this. According to Google's help page on finding cheaper flights, you can:

• Open the date grid (calendar) to see the lowest total price for each day. Prices there update about once every 24 hours.
• Use the price graph if your dates are flexible, to see fare trends by month or week.
• Check the airports insight to see fares from or to alternative airports.
• Browse popular destinations or the world map when you do not mind where you go.
• Sort by price, use the Cheapest tab, and filter by stops, airlines or times.

Run the same search a few times with different dates and write the cheapest total you see for each. After three or four searches you will know the realistic price range for the trip, and that range is your baseline.

3. Compare the total price, not the headline fare

Displayed prices usually leave out extras such as baggage, which vary by airline. A low base fare plus a paid cabin bag and a paid seat can cost more than a higher fare that includes them. Before you decide:

1. Add the bag you will actually bring.
2. Check whether the fare allows changes or cancellation.
3. Look at the airport you land at and how much it costs to reach your destination from there.

Google also notes that separate or self-transfer tickets can sometimes save money, but they may bring change fees per ticket, extra baggage work and a higher risk of missing a connection if a flight is delayed. Treat them as an option for experienced travelers with a long layover, not as a default.

4. Check nearby airports and both directions

A city with two or three airports often has different fares from each. Search each one, and also try flying into one airport and out of another (open-jaw). Compare the saving with the cost and time of getting to the cheaper airport.

If you live near several airports, this is the step that often matters most. With Cheap Flights Alert you pick your home airport when you sign up, and its alerts are based on how fares compare with that airport's recent history.

5. Set a baseline, then track the price

Once you know the normal range for your route, you can recognize a good price. Without that baseline, every fare looks plausible.

Google Flights lets you turn on Track prices for a route and set the stops, cabin class and number of tickets. According to Google's page on price tracking, you can track your searched dates or "Any dates" if you are flexible. For "Any dates" you get an email when the route's minimum price drops significantly over a month, and you may also get emails when prices are likely to rise. This works well when you already have a specific route in mind.

6. Let deal alerts watch the airport for you

Route tracking helps when you know where you are going. If you are flexible about the destination, it is easier to watch your home airport instead. Cheap Flights Alert is a free service that watches flight prices from the departure airport you choose and messages you when a fare is clearly cheaper than usual.

How it works, in short:

• Every fare is compared with recent prices seen from the same airport, which gives a deal score. Only deals scoring 80% or more are sent.
• You choose WhatsApp, Telegram or email, and opt in to each channel separately.
• Each alert has the price, the travel dates and a link to book with the airline or booking site.
• Sign-up is free, with an email magic link and no password. You can sign up for alerts here, and change airport or channels at any time.

There are limits. Cheap Flights Alert does not sell tickets or book flights, does not predict whether prices will rise or fall, and cannot guarantee that a fare is still available when you click. The final price is the one on the booking site. If you have a fixed route and fixed dates, a search tool with a date grid will usually fit better. You can read how the fares and the deal score work on the about page.

7. Book when the price is inside your range

When a fare falls inside the range you found in step 2, decide quickly. Fares can change or sell out at any time, so there is no reason to wait for a lower number once the price fits your budget and the terms (bag, change policy, airport) are right.

Before you pay:

1. Check the passenger names match the passports exactly.
2. Re-read the total, including bags and seats.
3. Check the cancellation and change conditions.
