How Weekendstop calculates time on the ground, badges and prices

The exact rules behind every number you see on the site

Where the prices come from

Prices are per person, return, from Google Flights data, in the currency you choose. Weekendstop does not sell tickets: the links on each trip lead to Google Flights or the airline's own booking page.

Live search: results are kept for up to an hour for month searches and 15 minutes for searches with exact dates, so the same search made twice in a short time does not ask for new data. City pages (for example cheap flights by departure city) are dated snapshots and show the day they were checked. Fares change quickly, so always check the live search before you book.

Google's data sometimes returns the cheapest fare with a long connection, for example a 14-hour journey on a route that is normally about an hour. We show the flight time and number of stops on every trip so you can judge for yourself.

Time on the ground ("time there")

For every trip we take the length of the trip in hours, subtract the two flights (out and back) and a 4-hour allowance for airport time, and show what is left.

Formula: trip length in hours − (flight time × 2) − 4 hours.

Example: a Friday-to-Sunday trip is 48 hours. With a 2-hour 20-minute flight each way, the flights take 4 hours 40 minutes, so the time there is about 48 − 4.7 − 4 = 39 hours. The same 48 hours with a 14-hour journey leaves a negative number, which is why such trips are hidden.

Trips with fewer than 12 hours on the ground are hidden by default. On the search page you can untick "Hide trips with little time there" to see everything. Trip length depends on how you search: with exact dates it is your departure date to the return date (your "days" setting), and with a month it is the trip length Google returns, usually 3 to 5 days.

The badges on the trip cards

Badges are worked out from the results on your screen, never chosen by hand or at random. A badge only appears when it really tells one trip apart from the rest.

The chart and the "Surprise me" treasure hunt

Chart: every dot is a destination. Flight time runs left to right and price bottom to top, so the bottom-right corner (shaded) means far away and cheap. A bigger dot means more hours on the ground, and the colour shows non-stop, one stop or two or more stops.

Treasure hunt: "Surprise me" hides the destination names and shows three closed chests with only the price, flight time and hours there. It draws from trips with at least 12 hours on the ground and at most one stop, respects your budget, and tries to avoid the most obvious cities. Opening a chest reveals the trip.
