How Kestrel Works

Start with your airport.

Pick the US airports you actually fly from — your closest, your cheapest, and maybe your parents'.

Watch the deals roll in.

We track airfare to more than 840 destinations worldwide. When a price drops, you hear about it.

Then book it.

Flight details, booking links, and how long the fare should last. All that's left is to say yes.

Booked. Boarded. Gone.

Most deals run 42–88% below normal fares, on itineraries actually worth flying. If it isn't a genuinely great price, we don't send it.

"I took a solo trip through Europe for $412. I flew into Barcelona and out of Lisbon, and squeezed in Marrakech on the way. Two weeks, and I still can't quite believe the price."

Renata V.Member

"An alert came through for Tokyo at $538 return and I messaged my partner before I'd finished reading it. We did Tokyo, Kyoto, Hiroshima and Osaka. He proposed on the last night in Kyoto."

Idris M.Member

"We'd talked about Spain for years and always decided the flights were too much. One Europe sale alert later and we paid about $674 for the two of us."

Colette B.Member since 2016

"Thanks for the heads-up on Denver to Rome for $351 last November. At that price I turned a solo trip into a proper family one with my wife and both daughters."

Sam O.Member since 2018

"I woke up to an alert for Atlanta to Hawaii, which basically never happens, and we'd booked within the hour. Completely impulsive, easily the best call we've made in years. $384 each, all in."

Never overpay for a flight again

Everything good about going somewhere, without the hours of searching to get there.
