Search answers and older articles still recommend KAYAK Trip Builder for working out the cheapest order to visit several cities. Here is what we could verify about it on November 11, 2026, and what does that job now. Stopover is one of the alternatives, and it is ours.
Change the cities and the dates to your own; Stopover prices every order they could go in and shows what each one costs.
No account needed to begin.
The only description we could find is Kiwi.com’s press release, dated January 21, 2020. It says KAYAK was “testing a new product feature” called Trip Builder that “finds the cheapest routes between cities,” and that it “uses Kiwi.com’s Nomad feature algorithm.” You would “enter your dream destinations and the duration you want to spend in each of them, and let Nomad shuffle the possible combinations and provide you with the best one.”
The address KAYAK used for Trip Builder now opens a KAYAK guide called “How to search for & book multi city flights,” dated May 12, 2026, which does not mention Trip Builder. It tells you to select “Multi-city” instead of “Round-trip” or “One-way” and to enter each leg, so you choose the order and KAYAK prices it. We found no Trip Builder option on KAYAK’s flight search on November 11, 2026. If it still runs somewhere on KAYAK, we could not find it.
Kiwi.com Nomad, the feature Trip Builder ran on. Kiwi.com describes it as letting you “input multiple destinations and your desired duration of stay in each of them, before it calculates the cheapest possible route,” and you book on Kiwi.com.
PanFlights, Optimized tour. Its page says that when the order, the dates and even which cities are open, “PanFlights calculates route suggestions for you,” and that bookings happen on external sites through its links.
Stopover (ours). A home airport, up to 7 cities, a window of dates and a range of nights per city; it prices every order on dates that fit together, shows the orders that came close, prices trains and buses where they win, and links each leg to where you book it. Free, no account needed for up to 3 trips a day. Try Los Angeles to Tokyo, Seoul and Bangkok.
How these compare, side by side, is on the Kiwi Nomad alternatives page, and how to work out the order yourself is in how to find the cheapest order for a multi-city trip.
We could not find it on November 11, 2026. KAYAK's flight search offered no Trip Builder option, and the address KAYAK used for it now opens KAYAK's general guide to multi-city flights, which does not mention it. If it still runs somewhere on KAYAK, we could not find it.
Kiwi.com's press release, dated January 21, 2020, says KAYAK was testing a feature called Trip Builder that "finds the cheapest routes between cities", that it "uses Kiwi.com's Nomad feature algorithm", and that you entered your destinations and how long to spend in each.
Kiwi.com Nomad, the feature Trip Builder ran on, is on Kiwi.com. PanFlights' Optimized tour works out route suggestions when the order is open. Stopover prices every order of up to 7 cities inside a window of dates, with trains where they win, free with no account for up to 3 trips a day.
Not by itself. KAYAK's guide says to select "Multi-city" instead of "Round-trip" or "One-way" and enter each leg, so you choose the order. It prices the order you give it.
Taken from each company’s own pages as read on the dates below. Those pages change, and they are the authority on what each tool does today. If KAYAK brings Trip Builder back, or it turns out to still run, this page will say so.
