We help you find cheap flights and never miss a price drop.
Butterfly Flights is a flight price search and alert service. You tell us where you want to go and when, and we keep checking prices for you. When prices drop, we let you know by email so you can book at the right moment.
1. Search. Enter your origin, destination, and travel dates. We search across airlines and display current prices.
2. Set an alert. Found a route you want to track? Create a price alert. No account is needed for a basic alert.
3. We monitor prices. Our system checks your route regularly — every 6 hours for free alerts, every 30 minutes for Pro users. We pull live price data from Google Flights to give you up-to-date information.
4. Get notified. When prices hit your target or drop significantly, we send you an alert so you can book before the deal disappears.
Everyone can use Butterfly Flights for free. Free users get one active alert with economy class searches and 6-hour price checks. Pro subscribers ($5/month) unlock unlimited alerts, all cabin classes, 30-minute price checks, an interactive booking flow with direct airline links, and an 11-month search window.
Butterfly Flights is built and operated by Ostira, LLC. We focus on making flight price tracking simple and reliable.
Set up a guest alert and we'll keep checking prices for you. No account needed.
