JetRadar Alternatives 2027: 12 Flight Sites in Ranked Order

JetRadar alternatives, ranked: 12 search engines, agencies, and deal alerts, plus why travelers switch and what changed when JetRadar became Aviasales.

JetRadar checks airlines and ticket agencies for a route and lists their prices side by side. JetRadar is now called Aviasales: in January 2021, its owner said Aviasales would replace the JetRadar brand, and JetRadar’s websites have since been switched over to Aviasales. The search engine works the same way under the new name.

Why Look for a JetRadar Alternative?

JetRadar shows you prices, and you pay the airline or agency you pick. Here’s why some travelers want something else:

You book with someone else — JetRadar doesn’t sell tickets, so any change or refund goes through the agency or airline you paid.
Agencies you don’t know — The lowest price may come from a ticket agency you’ve never heard of, so check its reviews before you pay.
One search at a time — Each search covers one route and one set of dates, and a low fare can come and go between searches.

The Three Kinds of JetRadar Alternatives

The options split into three groups by how they work:

Bigger search engines — Skyscanner, Google Flights, Kayak, Momondo, and Cheapflights compare sellers as JetRadar does, and you finish the purchase on another site.
Travel agencies and booking apps — Expedia, CheapOair, Kiwi.com, and Hopper are sellers: you pay them, and they issue the ticket.
Deal alerts — A deal alert service keeps looking while you aren’t searching. RatePunk is one: you set a home airport, and we send an alert when a flight from it falls below its usual price.

Pro Tips for Cheaper Flights

Set alerts for multiple airports: If you’re flexible, you’ll find better fares.
Book when alerted: Low-fare deals usually don’t last long.
Check different dates: Even shifting one day can mean big savings.
Plan ahead for popular seasons: Alerts can cover holiday travel and events.
