Searching a good deal for a flight ticket for my family. Going to fly in 6 months. That´s quite a lot of time to find a better deal.

Checking #skyscanner, #kiwi, #kayak, #flyaway, etc. but cannot simply find a feature to be notified as soon as the price will get under a specific value.. only when will be just discounted..

Does anyone know a good #app for it?
