Pick a route and a target price. Netletz queries the same live airline inventory the booking sites pull from — through the Duffel API, hourly within 30 days of departure (every 2–6 hours further out) — and alerts you on the next check after the lowest fare drops below your number. Exact dates or a flexible date window. Economy through First. Nonstop optional.

JFK → LAX, Aug 14 dropped to $312 (was $480). Tap to book before it pops back.
No airline accounts. No mileage programs. No app to keep open.
Origin and destination as 3-letter IATA codes. Pick exact depart (and optional return) dates, or set a 14-day flex window and a trip length — we'll check every departure in the window.
Max total price in USD. 1–9 passengers. Economy, Premium Economy, Business, or First. Toggle nonstop-only. We only ping when the lowest matching fare drops below your target.
On the next hourly check (every 6 hours for flex windows), if your number hits we alert you with the new fare, the target, and a deep link to the booking page. You skip the search.
Most fare trackers send a daily digest at 7am, even when the price hasn't crossed what you'd actually pay. Here's what makes Netletz different.
Your inbox has 47 unread emails. Your phone's notifications don't. We hit the channel you'll actually see in two minutes, not two hours.
Other trackers ping you when the price moves — even if it's still $700. We only fire when it crosses the line you actually set, then re-arm after it comes back.
Within 30 days of departure we check hourly; 30–90 days out every 2 hours, and further out every 6 hours. Flexible windows check every 6 hours since they fan out across many dates. We check around the clock, so drops are caught while you sleep.
Live Duffel API — not screen-scraped from a meta-search. The fare we alert you is the fare you'll see at checkout.
No Google login. No airline mileage program. No Chrome extension. Just a phone number, a route, and a target.
"Anywhere in a 2-week window, 7-night trip, under $500" is one watcher. Pin to Business class or Economy, nonstop or any. Pro covers 5 routes, Power covers 15.
Fictional examples in the real alert format. Fares come from Duffel.
JFK → LAX · Aug 14: Dropped to $312 (was $480). 35% below your $400 ceiling.
SFO → CDG · Oct 02: Air France dropped to $441 round-trip — first time under $500 in 6 weeks.
IAH → MEX · Nov 19: Aeromexico flash fare: $189 round-trip. Under your $250 target.
One missed flight deal or sold-out campsite costs more than a year of Pro.
Catch one thing you'd otherwise miss.
For the handful of things that always seem to slip through.
When 'first in line' is worth real money.
Every new account starts with 14 days of Power — 15 Watchers, 1-minute checks, texts and the AI page watcher, plus 1 ticket watcher at 2-hour checks, hourly in the final 48 hours. No card needed. Afterwards you move to Free unless you pick a plan; we remind you on day 11 and day 13.
Check speeds are the fastest each plan allows. Plan speeds apply to weather, metals, stocks, crypto and forex, and to campsites on Recreation.gov, California and Virginia. Page reads (Amazon, AI, webpage and ticket pages) run at most hourly, eBay listings every 2 hours, AutoTrader every 6 hours, gas station prices every 3–6 hours, ReserveAmerica campsites every 2 hours, flights every 2–6 hours until 30 days out, and domains once a day.
