Why Flight Weasel
Five ways to find a cheaper fare.
Multiple date searches
Search a whole date range at once
Pick a date range and Flight Weasel checks every departure and return inside it (every departure, for a one-way trip). That can be hundreds of date combinations, and we show you the cheapest days to fly.
Multi-origin searchNew
Fly from whichever airport is cheapest
Live near more than one airport? Search from up to six of them, or all of a city's airports, to the same destination in one go and see which departure is cheapest.
Advanced business class search
Premium cabins, deal prices
Filter by cabin, stops, journey time and airline to find Business and First Class fares worth taking. Each one shows its price per hour of travel and links straight to the airline.
Advanced alert system
Any route, watched for you
Set an alert on any route and we'll keep an eye on it for you. When a good deal turns up, we email you.
Advanced analytics
Know a real deal when you see one
Route insights show how each fare compares with what that route usually costs, so you can tell a good price from an average one.

Get the cheapest, emailed
When the search finishes we email you the best fares. They're often 30–70% below the going rate.
