You shouldn't have to check prices every day. Set your routes once — Zephyr watches around the clock and tells you when something worth booking actually appears.

How it works
Hundreds of routes from BER, FRA, AMS, and more — continuously, around the clock. Every combination of dates and destinations, so you don't have to.
Every fare gets a deal score from 1 to 5. Only 4 and 5 make it through — rare finds and exceptional fares. No filler, no noise. Rare finds are free; Elite unlocks the exceptional ones.
Get a push notification the moment a deal appears. Review the route intel, check your calendar, and we hand you off to Google Flights. No markups, no affiliate links — you book on your terms.
Real business-class fares Zephyr surfaced and price-checked. Snapshots from recent scans — live fares move fast.
Why Zephyr
The gap isn't technology. It's curation, timing, and no conflict of interest.
Google shows results when you search. We run searches in your name — every route, every day — and only alert you when something is genuinely worth booking.
Economy is a different market. We focus exclusively on Business — where deals are genuinely rare, savings are €500–2,000, and the experience is entirely different. First class is on the roadmap.
Every deal hands you off to Google Flights — you book wherever you want. No booking fees, no affiliate markups. Our only incentive is to surface something that's actually worth your time.
Natural language
No dropdowns. No date pickers. A few taps to set up a query — destination, budget, window — and Zephyr starts watching across nineteen airports. Change or pause any time.
20 European airports. Business class only. Free to start.
