Cheapest Way to Fly Multi-City in 2027: One Booking or Several?

A multi-city trip takes you to several cities in one go. You fly into one, travel overland, and head home from another, without doubling back to where you started. There are two ways to buy a trip like that. You can put every flight on one booking, which is what a multi-city search sells you, or you can make a separate booking for each flight. Which of the two you choose changes what you pay.

Let’s look at where to search, how to turn a long layover into a free stopover, and how to work out which of the two ways is cheaper for your trip.

Which Way of Booking Is Cheaper

Separate bookings are usually the cheapest option. Putting the whole trip on one booking narrows what you can be sold, in two ways.

• Fewer airlines. One ticket comes from one airline, so it can only hold that airline’s flights and flights from the airlines it works with. If the cheapest flight at one of your destinations is not on or connected to the same airline, you never see it in your results.
• Fewer seats. The cheapest seat on a flight is usually sold only to people booking that one flight and nothing else. Put it on a ticket with other flights and you get quoted the next price up.

Buy the flights one at a time and neither limit applies. Each booking stands on its own, so you can take the cheapest airline and the cheapest seat every time.

Two trips are worth booking together anyway:

• Flying out to one city and home from another — out to Paris and home from Rome, for example. On one booking, it is priced as a round trip. Bought separately it is two one-way tickets, and a long-haul one-way costs nearly as much as a round trip does, so you pay close to double.
• A round-the-world ticket — the price comes from how many continents you visit, not from adding up the flights, so a trip with more stops on it does not automatically cost more.

A single booking almost never wins inside Europe. The cheapest airlines there are the budget ones, and they don’t let anyone else sell their seats, so they can never turn up on a booking alongside other flights.

What a Single-Booking Multi-City Gets You

Putting every flight on one booking does three things for you.

• One booking for the whole trip — one reservation, one confirmation number, one place to change something when your plans move.
• One contract with the airline — if a flight runs late and you miss the next one, the airline has to get you there. On separate bookings, nobody agreed to connect them, and a missed connection is a new ticket at walk-up prices.
• No trip back to where you started — land in Paris, make your way to Rome, and fly home from Rome. On a normal round trip you would have to get yourself back to Paris to catch your flight home.

How to Plan the Trip, Step by Step

1. List the cities you want. Order does not matter yet.
2. Let a search engine put them in order. Nomad, Skyscanner, and Google Flights will each suggest a sequence. The cheapest order is rarely the one you had in mind.
3. Price the same trip as separate one-way tickets. This is the step that saves the money, and it is the one most often skipped.
4. Watch the layovers being offered. A long one in the right city is a free day out, and a long one in the wrong city is a day in an airport.
5. Book the cheapest option, unless a layover is short. One booking buys you the airline’s promise to get you there when a flight runs late, and that is worth paying a little for.

Some cities pair naturally because the flights between them are frequent and short. Paris, Rome, and Barcelona work as one European trip. Bangkok, Ho Chi Minh City, and Kuala Lumpur do the same across Southeast Asia.

How to Search Without Missing the Cheap Fares

Three things move the total more than anything else you can change: where you look, when you fly, and which airport you use.

• Search for the same trip in more than one place. Google Flights, Skyscanner, and Kiwi.com return different results for the same route, because they cover different airlines and combine them differently.
• Move your dates before you move anything else. A day on either side is often the whole savings driver, and the biggest sites will usually show you a month at a time.
• Try nearby airports. A secondary airport can cost noticeably less than the main one, and in most big cities it is not far away. Flying into Gatwick rather than Heathrow, or comparing JFK, LaGuardia, and Newark against each other, takes a minute and can sometimes vastly change the total.

Where to Search for Multi-City Flights

Four sites cover most multi-city searches.

• Google Flights — the fastest way to see a whole month at once. Its price graph shows how your dates compare, and you can set an alert on a route and let it tell you when the fare moves.
• Skyscanner — handles up to six flights in one multi-city search, which covers most trips.
• Kiwi.com — searches combinations other sites will not, because it stitches together airlines that do not sell tickets through each other. That is also the catch: those connections are not protected the way a single airline ticket is, so read what the Kiwi.com Guarantee covers before you rely on it.
• Nomad — Kiwi’s other search, and the only one of the four that picks the order for you. The rest make you fix the sequence of your cities before they will search. Nomad takes the list and finds the cheapest order, because the sequence you travel in changes the price.

Whichever you use, try a few different starting cities. Leaving from a different airport often moves the total more than changing your dates does.

How to Use a Long Layover

A long layover is dead time unless the airport is close to something worth seeing. How much you can do with one depends on which city you land in.

• Dubai — the Burj Khalifa and the Dubai Mall are the same complex, about 15 minutes from the airport by taxi or 40 by metro. Eight hours is comfortable.
• Istanbul — the airport is about 44 kilometers from the old city, and the round trip takes two and a half hours by metro. Going on your own, eight hours is not enough once you add passport control at both ends.
• Reykjavik — Keflavík is about 50 kilometers from the city, so the round trip eats most of a short layover here too.

A handful of airlines will get you into the city and back themselves. Turkish Airlines runs Touristanbul, free guided tours for passengers with 6 to 24 hours between flights, with pickup and return from the airport. That takes the traffic and the timing out of your hands, which is what makes an Istanbul layover work when going alone would not.

Several airlines will also let you have a longer layover for no extra charge, some of them will even put you up or give you discounted hotel rates while you are there:

• TAP Air Portugal — up to 10 days in Lisbon or Porto. No hotel included, so book your own.
• Icelandair — up to 7 nights in Iceland, or 21 on a Flex fare. No hotel included either.
• Turkish Airlines — a free hotel in Istanbul on layovers over 20 hours. From the US that is two nights in economy and three in business, more than most origins get.
• Emirates — a free hotel, meals, and airport transfers on connections of 6 to 26 hours, in every cabin. (You have to be on the shortest available connection, and your fare has to clear their minimum.)
• Etihad — two free hotel nights in Abu Dhabi, but only if you book directly rather than through an agent.
• Qatar Airways — a hotel in Doha from about $14 a night on layovers of 12 hours or more. They are the only airline that will put you up and still charge for it, though $14 a night is close to nothing.

Apply early. Most of these want at least three days’ notice.

Routes That Cost Less Than the Obvious Ones

Fares tend to follow demand, so the cities everybody flies to are rarely the cheapest.

In Europe, a loop through Budapest, Sofia, and Ljubljana usually prices below the same number of stops in France or Italy. Porto tends to cost less than Lisbon and sits on the same coast. Chiang Mai is generally cheaper to reach than Bangkok once you are already in the region, and quieter when you get there.

None of this is a rule, and it is the kind of thing that changes season to season. This is a good place to start when the obvious itinerary comes back more expensive than you hoped.

Your Multi-City Flight Checklist

Multi-city flights are worth the extra planning if you want to see more and pay less. Finding the cheapest options takes thought and preparation, but the rewards are worth it. Use this checklist to help you start planning your next trip today.

1. List your cities, then let a search engine choose the order.
2. Search the trip on Google Flights, Skyscanner, and Kiwi.com.
3. Price the same flights as separate bookings and compare.
4. Check whether a long layover earns you a free stopover.

Pricing the trip is the step that pays for itself. It takes time, but it is the only way to know which booking plan wins on your route. Prices will move with the airlines and the time of year.

The first flight of your trip leaves from your home airport, and its price changes from one day to the next. RatePunk keeps track of what flights from your home airport usually cost, and we alert you when one drops below that price.
