Weekendflights

Weekendflights shows flight prices for every weekend over the next 12 months in a color-coded calendar. Choose an origin and destination to see which weekends are deals, cheap, fair or pricey relative to that route's typical fare.

It pulls live fares from major flight aggregators every few hours, caches the cheapest option for each weekend, and sends travelers to the airline or aggregator to book. The full 12-month calendar is available without signup; a Pro tier adds filters for longer trips, weekday combinations and comparing up to five cities.
