Twenty seconds · silent by default

Watch any route. See its price history. Know a deal when you see one.

You book direct with our partner, so the fare is theirs, not ours — no markup, no games.

One honest footnote: airlines still charge their usual extras if you add a checked bag or pick your seat. That’s their menu — your fare is your fare.

Four deals to Europe.
Twice a week. Free.

The app searches whatever route you type, anywhere. The Four is the other half: twice a week I send the four best Europe fares from PHL, EWR, JFK, BWI, BOS and IAD — found by a machine, verified by a human first. Sixty seconds to read, then back to your evening.

Free, forever. Two emails a week. Unsubscribe in one click, no hard feelings.

Why this exists

Lewes, Delaware — July 2026

Goedenavond — good evening. I’m Peter: Dutchman in Delaware, frequently a little homesick.

I fly home to Amsterdam twice a year, and somewhere around the sixth crossing I got sick and tired of overpaying to hug my mom.
So I built a scanner: ~40,000 fares from PHL, EWR, JFK, BWI, BOS and IAD to Europe, checked twice a week. Then I built the app, so you could point the same machine at any route you liked.

It watches for me. Now it watches for you too.

Every edition comes from my own inbox, not a no-reply address. Hit reply — I read every one.

— Peter

How it works

A machine that hunts.
A human who checks.

01 · SCAN

The scanner sweeps

Twice a week, our scanner checks ~40,000 fares from six East Coast airports to 62 European cities, comparing every price to months of history.

02 · VERIFY

A human verifies

Every candidate is opened and checked by hand, live. Real airline, real dates, real bookable price. Nothing gets published unverified.

03 · SEND

Four land in your inbox

Only the four best make the cut. Most US fares include free 24-hour cancellation — lock the price now, decide over dinner.

The Premium Four

The machine finds deals hours before the free Four goes out. That gap is where the cheapest seats disappear. The Premium Four closes it:

  • INSTANT Deals the moment they’re found — not hours later
  • MISTAKE FARES The ones that die in hours and never wait for the next edition
  • YOUR ROUTE Your home city, checked three times a day — when something special appears, premium gets a same-day alert

The free Four stays free, forever. Premium members will be invited from the free edition first — subscribe above and you’re already in line.
