Flights from different airports to the same destination

What to keep the same, what to add up, and the three numbers that decide a group flight.

Updated

Flight search tools are usually built around one traveller leaving from one place. A group has several, and every comparison you make by hand multiplies: five people and ten possible destinations are fifty prices to find, write down and add up. This guide is about doing that comparison properly, with or without a tool.

Keep four things the same

A price only means something next to another price that was found the same way. For every traveller, keep these identical:

Add up three numbers for each destination

What to write down for each place
NumberWhy it matters
Group totalThe cost of the trip for everyone together. It is what you compare places on.
Highest single priceThe most any one person pays. If it is too high for them, the trip does not happen.
Longest journeyThe slowest trip in the group, with its stopovers. One person on a ten-hour itinerary can spoil a weekend.

Check what the price hides

A worked example

Three people fly from Berlin, Lisbon and Dublin to Barcelona on the same dates. The prices are invented for the example.

Round trip to Barcelona, per person (example)
From Price Stops
Berlin94 €Direct both ways
Lisbon71 €Direct both ways
Dublin88 €Direct both ways
Group total253 €Highest single: 94 €

Everyone is on a direct flight, nobody pays much more than anybody else, and the total is the lowest of the places the group looked at. That is what a good answer looks like: not the cheapest flight for one person, but a place that works for all of them at once.

Doing it with KupuKupu

KupuKupu is built for exactly this comparison. Each person adds the city they fly from, and it searches round-trip flights from every city, keeps the destinations that everyone can reach, and shows each person’s own price, the group total and the journey time. A filter keeps only direct flights.

It is free and needs no card. It does not sell tickets: prices come from Kiwi.com and Ryanair, and each person books their own flight there.
