Going (formerly Scott's Cheap Flights)
Going sends deals from the home airports you choose, by email, app notification or both, and watches fares to more than 900 destinations. It covers departures from US airports only: the 50 states, Puerto Rico, Guam and St. Thomas.
The free Limited plan covers economy deals within the continental US, with ads. Premium (US$49 a year) adds international deals and mistake fares from your home airport. Elite (US$199 a year) adds premium economy, business and first class, and mistake fares from every US airport. Going's guides mention a 14-day trial for first-time members. Deals are chosen by its Flight Experts, who weigh the price against the usual fare, the airline, the routing and how many dates are available.
Suits: anyone flying from the US who wants a person's pick of the best fares.
Dollar Flight Club
Dollar Flight Club emails deals from up to four departure airports on its paid plans (one on the free plan). Its help centre lists members in North America, Latin America, Europe, Australia and New Zealand. Its staff search fares by hand and send the ones they judge worth booking, so the destinations are a surprise.
The free Basic plan has a waitlist with no set timeline. Its help centre lists Premium at US$69 a year and Premium+ at US$99 a year, each with a 14-day trial; Premium+ adds premium economy, business class and text alerts for up to three dream destinations (US and Canadian numbers only). We found no current iPhone or Android app.
Suits: people happy with email who want a wide range of departure countries.
Secret Flying
Secret Flying publishes deals and error fares on its website for departures around the world, grouped by region, and has been running since 2014. You can also get email alerts for the departure cities you choose: up to 5 on the free plan, 10 on Standard and 20 on Premium, which adds business and first class deals and alerts for specific routes.
The paid plans arrived in April 2026; we couldn't confirm their prices when we checked. Its old app has gone, and alerts now come by email.
Suits: deal hunters who like to browse every deal, including error fares, from anywhere.
I Know The Pilot and I Want That Flight (Australia)
I Want That Flight is an Australian airfare comparison site, built in Melbourne. Its deals brand, I Know The Pilot, sends a handful of airfare and hotel deals a day by email, app and website for the closest of 11 Australian airports, and is free. On I Want That Flight itself you can also set an email alert for one route at a target price.
Suits: Australians who want free daily deal posts from their nearest airport.
FarePop
FarePop sends deals from the airports you choose in Australia, New Zealand, the US, Canada, the UK and Europe, in your own currency. Instead of a person's pick, every fare is measured: it's compared with what the same route usually costs for the same trip length and dates, and only fares at least 25% below make the cut (20% for a good fare). A full-service airline selling at a budget price is compared with other full-service airlines instead, and labelled that way. Each fare is checked again on its exact dates before you hear about it, and withdrawn if it goes.
Each deal shows the usual price, the discount, the flights each way and the weather for your dates. The rules are published in full in our savings methodology.
Suits: people outside the US, or anyone who wants to see the numbers behind each deal.
