Cheap flights are low-cost tickets typically offered by both budget and full-service airlines at significantly lower rates than other available fares.
Most airlines use dynamic pricing systems to continually adjust fares based on factors such as demand, availability and booking patterns. Generally speaking, the lower the demand, the lower the price; the higher the demand, the higher the price. This rule applies to both no-frills carriers and traditional airlines.
For example, if you wanted to book a cheap flight this summer from London, the key to saving money is knowing exactly where, when, and how to book the most economical option.
The most efficient way to start your hunt for low fares is by using a flight comparison website. These platforms scour hundreds of airlines and online travel agents to find the best deals for your route.
Many also offer powerful tools like flexible date calendars, price predictors, and alerts that let you track airfares and book at the optimal moment.
The most famous of these websites include:
The problem with these sites, however, is that they each employ different partnerships, search features, data sources, and pricing algorithms, which means the lowest final price might appear on one website one day and on another the next.
The ultimate solution is to compare results from several flight comparison sites to ensure you find the cheapest ticket from a booking provider you trust.
Flights Finder is a meta-meta search® engine that aggregates the results from the top airfare comparison sites into a single, easy-to-use dashboard. Our platform lets you quickly compare prices head-to-head across Skyscanner, Kayak, Google Flights, Cheapflights, Momondo, Kiwi, Jetradar/Aviasales, and more.
This method gives you a much greater chance of finding the cheapest available fare, combining multiple powerful search networks into a single, comprehensive platform. In fact, in our flight comparison study, we found it is not uncommon to save £50–£100 per passenger simply by cross-checking the best comparison sites, especially on long-haul routes.
In a recent test by Flights Finder, a week-long return flight from London to Phoenix in December showed significant price variation. Skyscanner listed the cheapest non-stop option at £1,959, while Kayak showed the exact same itinerary for £1,856. That is a saving of £103 per person, or £412 for a family of four.

Comparison sites are great at ‘finding’ the cheapest airfare, but they don't actually ‘sell’ you the ticket. They act as large digital directories which show you which airline or travel agent has the best price. Once they have found you the cheapest flight, they will redirect you to an airline or online travel agent to complete your booking and purchase your flight.
Using an established comparison engine is considered safe as it is just a search tool, the important part is seeing who is actually selling the dispayed ticket. By comparing the comparison sites, you also get to compare the different providers behind the prices. We always recommend checking third-party reviews of travel agents you may be referred to before parting with your hard-earned cash.
Some comparison sites, such as Google Flights. Kayak and Skyscanner, give you the option of booking directly with the airline on most routes, which many people prefer if they don't feel at ease booking through a third-party agent.
Flights Finder makes it easy to identify the cheapest available flight, presenting multiple booking options for the same itinerary and allowing you to choose whether to book directly with the airline or through an agent, whichever feels most comfortable.
We present a much greater selection of booking options than a single comparison site can offer alone. You have the choice of selecting a slightly more expensive, or cheaper option based on how you feel about the vendor of the ticket:
| Comparison Site & Price | Booking Provider | Star Rating |
|---|---|---|
| Kayak - £448 | Booking.com | 4.9 |
| Skyscanner - £448 | Lastminute.com | 4.6 |
| Google Flights - £464 | Lufthansa (Airline) | 4.6 |
| Momondo - £458 | Norse Atlantic (Airline) | 4.1 |
| JetRadar - £490 | Budgetair | 3.8 |
| Cheapflights - £476 | TravelUp | 4.8 |
(Star ratings provided by Skyscanner. Prices shown are based on a sample route for flights to Orlando from London in July 2027 and subject to change.)
You can also compare cheap one-way flights, utilise flexible date flights, evaluate multi city flights, find business class flights, explore first class flights, and more.
It is highly unpredictable which site will offer the lowest price. This is especially true once you apply your preferences, such as departing at specific times or adding extras like checked baggage.
The best strategy to locate the most economical ticket is to use Flights Finder. Our dashboard allows you to cross-check all major comparison sites within seconds, maximising your chances of getting the best deal for your specific needs.

Alternatively, you can browse our dedicated destination pages to view the latest real-time flight deals grouped by region:
You can also utilise our Flights Finder Deals Carousel below to uncover budget-friendly destinations.The carousel will automatically display the best prices uncovered by fellow travellers within the last few days.
The downsides of booking the cheapest flight you can see may be multiple:
FlightsFinder lets you quickly apply filters for particular airlines, checked bags, departure/arrival times, duration, and stopovers, making head-to-head price comparison easy.
Always compare budget carriers with full-service airlines. Full-service options are often less stressful and can sometimes cost less overall.

Travel agents can sometimes secure cheaper flights by buying tickets in bulk, mixing and matching competing airlines, or lowering fares to encourage lucrative add-ons like hotels and car rentals.
If you find that a travel agent is significantly cheaper on a specific route, we suggest booking through them only after checking independent reviews of their service. However, if the savings are minimal, it is best to book directly with the airline, as dealing with changes, cancellations, and customer service is generally much easier.
A hidden-city ticket is when it is cheaper to buy a flight with a layover and get off at the connection point rather than booking a direct flight. For example, if you want to fly to Rome, you might find it cheaper to book a flight to Türkiye that includes a stopover in Rome. The strategy involves disembarking at Rome and simply discarding the final leg of the journey.
While this travel hack can save you money, it comes with important caveats. First, you cannot travel with checked luggage, as those bags will automatically continue on to the ticketed final destination. Second, this practice violates the airline's contract of carriage, which could result in the airline invalidating your frequent flyer miles or banning you in a worst-case scenario.
Flights Finder displays available hidden-city ticket options via Skiplagged, which you can easily search directly through our all-in-one dashboard.
You can scan for error fares quickly using Flights Finder's broad "Everywhere, Anytime" search functionality as noted in this LA Times article about ultra cheap fares.
We also manually track and post the best mistake fares and jaw-dropping flight discounts directly to our community channels. Be sure to follow us on TikTok, Instagram, and YouTube so you never miss a flash deal.
No, it is a persistent myth that individual searches drive up airline prices. Fares are controlled by automated dynamic pricing models that are based on seat availability and global sales. Route studies by FlightsFinder show that prices fluctuate naturally and often decrease during heavy research. Incognito mode is useful for hiding your search history, but it does not unlock cheaper fares.
Yes, it can sometimes be cheaper to book your ticket in a foreign currency due to shifting exchange rates. An effective strategy involves changing the regional point-of-sale market within your chosen search platform to compare localised prices side-by-side.
Flights Finder makes this process effortless. By selecting a different territory from our dropdown country selector, our dashboard instantly surfaces all available aggregator fares published specifically for that geographical market.
Please note that you should always review the provider's terms and conditions before purchasing a ticket through an alternate regional market, and check if your credit card charges international transaction fees.
In our experience, for short-haul flights, the optimal booking window is 1 to 3 months before departure. For long-haul itineraries, it is generally best to secure your tickets 2 to 6 months in advance.
Because airline ticket pricing is not an exact science, we highly recommend monitoring fares using a flexible date calendar or setting up automated price alerts for your specific route. These tracking features can be configured quickly and easily on most major comparison platforms.
Tuesday and Wednesday departures can sometimes be cheaper because demand is often lower, but there is no universally cheapest day to fly.
The most efficient way to verify current rates is to utilise a flexible date calendar. Flights Finder offers an interactive grid calendar that makes it easy to spot the lowest-priced travel days. We recommend using our grid alongside other comparison tool matrices to ensure you capture the absolute best deals available. Beware, however, that a lot of flexible date tools are based on historical searches so it all depends on availability.
The world's most prominent low-cost carriers include AirAsia, easyJet, Eurowings, Jetstar Airways, Ryanair, Scoot, Southwest Airlines, TUI, Vueling Airlines, and Wizz Air.
Flights Finder searches the vast majority of these budget operators via our integrated comparison engines. However, please note that select carriers, such as Southwest Airlines, do not share their pricing data with some third-party comparison sites, but they do show up on Google Flights.
A phantom fare occurs when you spot an exceptionally low price on a flight comparison site, but the moment you click through to book, the fare suddenly vanishes or increases substantially.
While this is highly frustrating, it typically happens because data aggregators pull ticket pricing from multiple external sources, causing a slight cache lag before surfacing the most up-to-date rates. Alternatively, that specific low-cost seat tier may have simply sold out during your search session, as live airfares are constantly traded in real time.
The best workaround is to utilise Flights Finder. Because our dashboard lets you view multiple alternative booking options from various search engines simultaneously, a sold-out fare on one site can be quickly cross-referenced to see if it remains available to book on another platform.
"Our flight data shows that you should cross-check at least four separate leading price aggregators (after applying filters) to be sure you've caught the best deal. If you book through an online travel agent, make sure you check third-party reviews before parting with your money."
