The most customizable flight alert app
Kestrelia monitors flight prices around the clock and alerts you the moment a fare matches your exact criteria. Not a generic digest — THE flight you've been waiting for.
What is Kestrelia?
Kestrelia is a flight alert and flight intelligence app. You define exactly the trip you want — routes, budget, flexible dates, cabin, layovers, baggage, airlines, time windows — and our engine watches prices 24/7 across multiple providers. When a flight matches, you get an alert by email, push notification or SMS.
Where most tools blast the same "deals" to everyone, Kestrelia is built for demanding travelers: 31+ combinable criteria so you only ever see fares that are genuinely relevant to you. This is precision fare intelligence, not another newsletter.
We're neither a travel agency nor a booking middleman: Kestrelia is a pure-SaaS monitoring tool. When a fare works for you, we redirect you to the booking channel — fully transparently.
Our mission
To make airfare intelligence accessible to everyone. Flight prices change thousands of times a day; we turn that chaos into one clear alert, at the right time, on the flight that matters to you.
Our vision
To become the reference for personalized flight alerts — the tool travelers choose when they want full control over what they track, instead of one-size-fits-all recommendations.
The flight intelligence engine
What separates a real fare-watch app from a simple deals newsletter.
31+ precision criteria
Multiple routes, budget, flexible dates, cabin, number of layovers, max duration, preferred or excluded airlines, baggage, time windows: combine them so you only get flights that truly match you.
Multi-provider monitoring
We query several flight data sources (Amadeus, Duffel and more) with automatic failover. More coverage, fewer blind spots, no reliance on a single provider.
Price history & median
Kestrelia builds a per-route price base to know what a "normal" fare looks like and spot real drops — not just an isolated number out of context.
Buy now or wait?
By analyzing price trends, Kestrelia helps you decide whether to book now or hold — so you buy at the right time, not just the right price.
Real-time alerts
The moment a fare crosses your threshold, you know. We only re-notify the same offer if its price drops significantly again — zero spam.
Email, push & SMS
Get alerts on the channel you prefer. Tune cadence and priorities to stay informed without being overwhelmed.
Why Kestrelia over generic alerts
Built for travelers who want control, not a list of average deals.
The right flight, not 5 random deals
Going and Hopper send a few curated offers to their whole audience. Kestrelia sends THE flight that ticks your 31+ criteria — yours, not the average.
You configure everything
Every parameter is in your hands: routes, budget, layovers, airlines, date windows. You watch exactly what you want to watch.
Transparent, no conflict of interest
We don't sell tickets and never push an offer to earn a commission. Our only job: alert you at the right time, honestly.

Who's behind Kestrelia
Kestrelia is founded by Sergio Nokam, a developer and traveler tired of receiving "deals" that never matched his real needs. The idea: a fare-watch tool where the traveler decides everything they monitor. The product is currently in pre-launch, built independently, with a commitment to total honesty — no inflated stats, no promises the product doesn’t yet keep.

Frequently asked questions
Everything you need to know about the Kestrelia flight alert app.
What is a flight alert app?
A flight alert app monitors airfare prices and notifies you when they drop. Kestrelia goes further: instead of generic alerts, you set 31+ criteria (route, budget, layovers, cabin, flexible dates, airlines…) and only receive the flights that truly match you.
How is Kestrelia different from Going or Hopper?
Going sends a few curated deals to its whole audience; Hopper is mainly a mobile booking agency. Kestrelia is a precision monitoring tool: you configure every criterion and receive THE flight that matches your parameters, not an average selection for everyone.
How does Kestrelia flight intelligence work?
We continuously query multiple flight data providers, build a per-route price history to know the "normal" fare, detect real drops, and estimate whether it’s better to buy now or wait. You get one clear alert at the right time.
Is Kestrelia free?
Kestrelia will offer a free tier with basic alerts, plus paid tiers for advanced monitoring and real-time cadence. The product is in pre-launch: join the waitlist for priority access and Founding Member pricing.
Which countries and routes are covered?
At launch, Kestrelia covers Canada (Montreal, Toronto, Vancouver, Quebec City, Ottawa…) and the USA, with major transatlantic routes. Europe follows in 2027, then a gradual global rollout.
How will I receive my alerts?
By email, push notification or SMS — your choice. You set the cadence and priorities, and we avoid spam: the same offer is only re-notified if its price drops significantly again.
