FlyDown

FlyDown watches low-cost airlines (Ryanair, easyJet, Wizz Air, Vueling, Volotea, Transavia) for you. Pick the airports you fly from and the most you want to spend: when a return trip drops under your budget, you get an alert by email, Telegram or push. Every trip gets a Flappy Score (0–100) that weighs price, flight times and comfort, so the cheapest isn't automatically the best. Free, no credit card, in 6 languages.
