What the numbers say about flying through Geneva International Airport
PlaneSane doesn't yet have on-time and cancellation history for Geneva International Airport, so it isn't scored for departure reliability here — that record currently covers the US, UK, Brazil, and Australia. The weather and connection context below comes from separate global sources and still applies.
On weather, Geneva is an unusually calm-weather airport year-round. April is the calmest stretch for flying, scoring 99 out of 100 for favorable conditions, while December is the most disruptive at 87, driven mainly by low visibility & fog and snow. The year is relatively steady, so no single month stands out as one to avoid on weather alone.
If you're connecting through GVA, give yourself room. An international transfers around 70 minutes once immigration and a bag recheck are in the mix. Those are floors, not comfortable buffers — one inbound delay can erase them, so add margin when the connection matters.
None of this guarantees your specific flight — it’s the backdrop. To turn it into a booking, score real flights to Geneva, read how we weigh it all in how the Peace of Mind Score works, and brush up with how to pick a reliable flight and avoiding weather delays.
