Description

Tired of flight searches that show a low number without telling you whether it is actually a good price? Cheap Flights Alert compares every fare with the usual price on that route, from airports worldwide, so you can see which drops are real. THE PROBLEMS IT SOLVES "Is this fare actually cheap?" Every fare is compared with the median of all fares we have seen on that route for departures in the next 12 months. You can also paste in a fare you found, and it tells you whether it is great, good, typical or high. "Where can I go on my budget?" Give your airport and a budget, and optionally a month or a country. You get the cheapest places, one fare per destination. "When should I fly?" See the cheapest dates and the cheapest fare of each month on a route, and what moving your trip by up to 3 days saves. "Would another airport be cheaper?" Compare several departure airports for one destination in one currency, or find the airports around yours. "My airport is never covered." Ask about any of more than 3,600 airports with scheduled flights. When a small airport has no fares, you get nearby airports that do. "I do not want to keep checking." Sign up on our site for a weekly email with the best fares from your airport. "Now I need a hotel and data abroad." Results link to our partner sites for the rest of the trip: Klook for hotels, Yesim, Saily or Airalo for eSIMs. You choose which one to use. GOOD TO KNOW No account is needed to look up fares. Prices are the latest fares we have seen and can change or sell out; the booking site always has the final price. Hotel and eSIM prices are on those sites, not in the results. Cheap Flights Alert does not sell tickets. Many booking, hotel and eSIM links are partner links, and we may earn a commission at no extra cost to you. Booking links can open a short page on our site first, where you choose the site and can sign up for alerts.

Tools

12 tools agents can invoke

Today's cheapest round-trip flight deals from any departure airport in the world (IATA code), cheapest first. Each deal has the destination, price, the usual price on that route and how far below it the fare is, travel dates, and a booking link. Also returns the airport's lowest fare in the last 30 days. Prices are in the departure airport's local currency. Small airports can have no fares; nearby airports with fares are then included.
cheapest_deals_from_airport
Which departure airport is the cheapest for one destination: the lowest round-trip fare from each airport, in one currency, cheapest first. Give a list of airports, or one airport to compare with those around it. Use this instead of calling deals_to_destination for each airport.
compare_departure_airports
The cheapest round-trip fares from a departure airport to one city, airport or country, with the usual price on the route when it has enough history. Works for any route with a recent fare, not only today's biggest deals. An empty result means no recent fare was seen on that route, not that no flights exist.
deals_to_destination
How Cheap Flights Alert decides a fare is a deal: the usual route price it is compared with, the minimum discount, and how often alerts are sent. With an origin and destination airport, also shows today's tracked fare on that route, its usual price and discount.
explain_deal_score
When a round trip on one route is cheapest: the cheapest dates, the cheapest fare of each month in the next year, the usual price, and what moving a planned date by up to 3 days saves. Use it for questions like 'when is it cheapest to fly' or 'can I save by moving my trip'.
flexible_dates
A link to the Cheap Flights Alert sign-up page with the departure airport filled in. It does not sign anyone up: the person enters their email and agrees to the privacy policy on the site. Alerts arrive as a free weekly email with the best fares from that airport.
get_alert_signup_link
Links to search hotels on our partner sites. The person may need to enter the city and dates there. It returns no hotels or prices, so never state a hotel price from it. Fare results already carry hotelsUrl.
find_hotels
Judges a round-trip fare someone found: great (40%+ below the route's usual price), good (20%+ below), typical, or high, with the usual price and the cheapest fare seen. Returns unknown when the route has too little history, instead of guessing.
check_fare
Other airports near an airport, nearest first, with the distance and the lowest fare currently stored for each. Use it when someone could depart from a different airport to fly cheaper, or when their airport has no fares.
nearby_airports
Find any airport with scheduled flights, worldwide, with its IATA code, by city, airport name, IATA code or country. Up to 20 results, busiest first. routesWithFares says how many destinations recently had fares from it; 0 means few or no fares, so a nearby airport may work better.
search_airports
Links to buy a travel eSIM for a destination's country, on several sites so the person can choose (Yesim, Saily, Airalo). It returns no plans or prices, so never state an eSIM price from it. Fare results already carry esimUrl.
find_esim
Places someone can fly to from an airport for a budget, cheapest first, one fare per destination, optionally in one month or one country. Use it when the person has not decided where to go. Prices are in the departure airport's local currency.
