SunnyFlight emails you when a cheap weekend flight from your city coincides with a sunny forecast at the destination. Here is exactly what happens behind that one email.
Every Wednesday, we pull fares for the coming weekend (Friday to Sunday) across all direct routes from your departure airport, using Travelpayouts flight data. Connecting itineraries are discarded — on a 48-hour trip, layovers aren't a discount, they're a tax.
Every destination that passes your price and flight-time filters gets a weather check against the Open-Meteo forecast for the exact weekend dates: daytime temperature and precipitation probability. If the forecast misses your minimum temperature, the deal is dropped — however cheap it is.
You get at most one email a week, with the top three matches. No deal that week? No email. The result is a signal you can act on: if SunnyFlight lands in your inbox, there is a bookable, cheap, sunny weekend on the table.
You define both: maximum price, maximum flight time and minimum temperature are set when you subscribe and can be changed anytime. Defaults are a $300 round-trip cap, 5-hour flight cap, and a 20°C minimum.
Thirty seconds of setup, then the searching is our job forever.
Get free weekly alerts →Flight prices come from the Travelpayouts/Aviasales flight-data API, covering published fares across hundreds of airlines. Prices shown are recent search data; the booking page always shows live availability.
Weekend forecasts are checked against Open-Meteo, with WeatherAPI.com as a fallback. A destination only qualifies if the forecast meets the subscriber’s minimum temperature with low rain probability across the weekend.
On a two-day trip, a layover can consume a quarter of your time away. SunnyFlight filters for non-stop routes so the weekend stays a weekend.
Booking links carry an affiliate code, so partners pay a small commission on completed bookings. This never changes the price you pay, and deals are ranked purely by price and weather — never by commission.
