Wingman - Watches your flight's price and pings you when it drops

Hi Product Hunt! I'm Roman, a software engineering student at the Czech Technical University in Prague, and I built Wingman on my own.

Erasmus taught me that new places and people's stories are worth the fare, and that "flights are too expensive" is mostly the price on the day you looked. I kept re-checking the same trips by hand, so I built something that does it for me.

How it works: tell Wingman where and when you want to fly. It keeps searching live fares for those exact dates and sends a notification to your phone or computer when the price drops or a faster flight shows up.

• Two records per trip: the cheapest flight, and the fastest one door to door, layovers included

• A buy-or-wait verdict on every price, with its reasons, and an optional target price it stays quiet above

• Round trips with one total, up to 9 travellers, any cabin, with or without bags, in 29 currencies

• Self-transfers through a hub, and a city covers all its airports (London means every London airport)

• Explore without an account: pick an airport and a month, and see where you can fly cheaply

Wingman doesn't sell tickets: each flight opens for booking with the airline or on Kiwi.com.

Pricing: one round trip is free, checked twice a day. Any other trip can have a Trip Pass, paid once, no subscription: €1.99, and your first one is €0.99. A pass checks the trip about every 20 minutes in the last three weeks before departure and adds flexible months, weekends and nearby airports.

It's a web app for now, in 16 languages; native iPhone and Android apps are on the way.

I'd love your feedback: which route are you watching, and what would make you trust an alert enough to book?
