Multi-city and open-jaw flight search compared — which tool builds complex itineraries cleanly and where self-transfer OTAs hide connection risk.

Key takeaways

Which tool is best for multi-city flight search?

Link to this answer

Google Flights multi-city builder is the cleanest starting point for open-jaws on one or two carriers. ITA Matrix exposes routing control power users need. Kiwi finds multi-carrier self-transfers Google will not merge. Skyscanner and Kayak multi-city exist but need careful handoff vetting.

Build in Google, verify on Aviasales/Kiwi, ticket airline-direct when the itinerary is one-carrier — see when booking direct wins.

Open-jaw versus multi-stop — search tips

Link to this answer

Open-jaw (fly into city A, out of city B) often prices better as one multi-city search than two one-ways. Stopovers added deliberately can be cheaper than separate tickets if the airline publishes a stopover fare — Matrix reveals these; metasearch may hide them.

Avoid impossible connection times even if the tool allows them — MCT exists for a reason.
