Quick answer:
Google Flights multi-city lets you build up to five flight legs in one search, which is how you price an open-jaw trip (fly into one city, home from another). Expect to work with fixed dates: the price graph, date grid and price tracking are built around a single city pair and do not carry over. |
What is multi-city search on Google Flights?
Google Flights has three search modes: round trip, one way, and multi-city. The first two ask for one city pair. Multi-city asks for a list of them.
That difference is the whole feature. Instead of one origin, one destination and a return date, you get a stack of rows, each with its own departure city, arrival city and date. Google prices the stack together and shows you the total.
Two kinds of trip need this mode. The first is an open jaw: you fly into one city and home from another, covering the gap yourself by train, car or a separate flight. New York to Rome on the way out, Venice to New York on the way home. The second is a genuine multi-stop run: three or more cities in sequence, like Los Angeles to Tokyo, Tokyo to Bangkok, Bangkok to Los Angeles.
Both are ordinary, airline-sanctioned ticket constructions. They are not workarounds, and they are not the same thing as hidden-city ticketing, where a traveler books a segment they intend to skip. In a multi-city itinerary you fly everything you paid for.
How to do multi-city on Google Flights, step by step
The mechanics take about a minute once you know where the controls are. The order matters, though, because two of these steps are easy to do in the wrong sequence and quietly narrow your results.
1. Price the plain round trip first.
Before you touch multi-city, search your main city pair as an ordinary return and write the number down. That is your baseline. Every complex construction has to beat it or justify the extra planning. Skipping this step is the single most common reason people conclude that multi-city "does not work" when in fact they never had anything to compare against.
2. Switch the trip-type dropdown to Multi-city.
On desktop it is the leftmost control above the search fields, defaulting to "Round trip". Click it and choose "Multi-city". The form redraws as a set of stacked rows rather than a single line.
3. Set passengers and cabin before you fill in the legs.
These controls sit next to the trip-type dropdown and apply to the whole itinerary. Setting them afterwards can re-run the search and clear entries you have already made. On passenger count, one habit is worth keeping: search for the number of seats you actually need, but understand that airlines release cheap seats in limited batches, so a search for four passengers prices all four at the highest bucket needed to cover the group. If you are booking for a group, price one seat first to see the true floor, then search the real number. The mechanics behind this are covered in our guide to how airline pricing works.
4. Fill in leg one, then let leg two autofill.
Enter the departure city, arrival city and date for the first row. The second row's departure field usually populates with the first row's arrival city. That default is correct for a continuous multi-stop trip and wrong for an open jaw, so overwrite it when you are building a jaw.
5. Add legs with "Add flight".
Each click adds another row. You can leave gaps in the sequence: the legs do not have to chain end to end, and a deliberate gap is exactly what makes an open jaw an open jaw.
6. Widen each field before you search.
You can enter more than one airport in a single field by separating them with commas, so a New York leg can read JFK, EWR, LGA rather than one airport at a time. This is the cheapest improvement available in multi-city mode, because it substitutes for the flexible-date tooling you do not get here.
7. Search, then check the Best and Cheapest tabs separately.
The default Best ranking blends price against duration and connection quality. On a multi-leg itinerary those two can diverge a lot, so look at both before deciding.
Common pitfall: people build all five legs, get an unappealing total, and give up. On a multi-leg search the total is often being dragged up by one badly priced segment. Try removing legs one at a time to find the offender before you abandon the shape of the trip.
How to book an open-jaw flight on Google Flights
An open jaw is the most useful thing most travelers will ever do with this form, and it only needs two legs.
Set the trip type to Multi-city. In row one, enter your home airport and your arrival city. In row two, overwrite the autofilled departure city with the city you are actually flying home from, and set your home airport as the destination. That is it. Two rows, one gap, one ticket.
Fly into Rome, out of Venice. Fly into Bangkok, out of Hanoi. Fly into Dublin, out of Edinburgh. The gap between them is yours to cross, and that ground segment is a real cost that belongs in your comparison, not a rounding error.
Airlines have priced this shape for decades, and on international routes it often comes back close to a comparable round trip rather than close to two one-way tickets. The full explanation of why, along with the three types of jaws and the cases where the math stops working, is in our guide to open jaw flights. What matters here is that Google Flights will price the construction for you, and the multi-city tab is the only place on the site where you can ask it to.
How many flights can you add to a multi-city search?
Google Flights caps a multi-city search at five legs. There is no setting that raises it.
For most trips this is not the binding constraint people expect. A destination open jaw needs two. A three-country run needs three or four. Five legs is already a complicated ticket.
If your trip genuinely needs more, you have three options, in rough order of how well they usually work:
Split the trip into a jaw plus separately booked middles. Book the long-haul in and out as a two-leg open jaw, then buy the regional hops separately, often on low-cost carriers that would not have appeared in the construction anyway. This is usually both cheaper and more flexible than forcing everything onto one ticket.
Drop legs you can cover on the ground. A leg you can replace with a train is a leg that does not need a fare.
Have an agent construct it in a GDS. Airline reservation systems handle multi-segment fare construction that consumer search boxes do not expose, and the ticketing limits there are different from Google's interface limit.
There is a real argument against cramming everything onto one ticket even when you can. Long chains of segments on a single ticket are protected end to end, which is the upside, but they are also harder to change after the first segment is flown, and on many carriers a change to one leg reprices the whole itinerary.
Google Flights multi-city limitations: what you lose from round-trip search
This is the part most guides skip, and it is the practical difference between multi-city and the other two modes.
Google Flights' flexible-date tooling is built around one origin and one destination. The price graph, the date grid and the Any dates version of price tracking all assume a single city pair with a trip length attached. A five-leg itinerary has no single city pair, so those tools have nothing to plot.
In practice, when you switch to multi-city you should expect to be working with fixed dates and no visual price comparison across days. Three workarounds cover most of the loss:
Track each leg as its own one-way search. Run leg one as a one-way, turn on Track prices, then do the same for leg two. You get alerts on the components even when you cannot get them on the construction. Setup details are in our guide to Google Flights price alerts.
Find your dates in round-trip mode, then rebuild. Use the price graph on the closest equivalent round trip to identify the cheap week, then take those dates into the multi-city form.
Use comma-separated airports instead of flexible dates. If you cannot flex on time, flex on geography.
Explore, Google's destination-discovery tool, is also a round-trip and one-way instrument. It will not plan a multi-stop route for you. Use it to decide where the far end of your jaw should be, then come back to the multi-city form to price it.
One ticket or separate tickets: how to read multi-city results
A multi-city search can return two structurally different things that look nearly identical on screen, and the difference decides what happens to you when a flight is late.
The first is a single constructed itinerary on one airline or one alliance, issued as one ticket. If leg one is delayed and you miss leg two, the airline owes you rebooking.
The second is a combination of separately ticketed flights that a partner has stitched together for display. That sentence is doing a lot of work. On a genuinely single ticket, the airline's obligation is clear. On a stitched combination, each ticket stands alone, and a missed onward flight is your problem and your cost.
What to check before you commit:
Whether one airline is operating and ticketing the whole thing, or whether the itinerary spans carriers with no partnership.
Check whether the fare display mentions self-transfer, separate tickets, or a separate booking. If it does, you are looking at components, not a ticket.
Whether the booking confirmation gives you one record locator or several. One six-character code across all legs generally indicates one ticket. Several codes means several tickets, whatever the search page implied. Our guide to how a PNR works on return flights covers what that code actually governs.
Bag fees, per leg. Google Flights has a bags filter that folds carry-on and checked bag costs into the displayed price. On a four-leg itinerary across mixed carriers, bag policy can differ leg by leg, and the difference can be larger than the fare gap you were optimizing.
Cabin, per leg. The cabin selector applies to the whole search. If you want business on the long-haul and economy on the short hops, you are looking at either a mixed-cabin construction an agent builds, or separate bookings.
Why Google Flights multi-city costs more than a round trip
This is the most common complaint about the feature, and it is usually not a bug.
Two things drive it. The first is fare construction: whether the airline's pricing system can assemble your legs into one fare or has to fall back on stapling one-way fares together. Constructions tend to price well when the far-end cities sit in the same region and badly when they do not. Fly into Rome and out of Tokyo and you are not really asking for an open jaw, you are asking for two long-haul one-ways.
The second is fare-class availability. The cheapest buckets on a route are not always open to multi-city construction, so your jaw can price from a higher bucket than the round trip you compared it against. Same flights, different inventory, different number.
Neither of these is something Google Flights controls. It is showing you what the airlines' systems return. Both are covered in more depth in our open jaw flights guide.
The practical response is to price the trip three ways before deciding: as a plain round trip, as a multi-city construction, and as separate one-ways. Then compare totals, with bags, seats and the ground segment added to each. A construction that saves on airfare but increases ground transport costs has not saved anything.
When Google Flights multi-city is not working
A short troubleshooting list for the failures people actually hit.
No results at all. Usually one leg is impossible as entered: no service on that date, or an airport pair with no partner-supplied inventory. Remove legs one at a time until results return, and the last one you removed is the problem.
Wildly high total. See the section above. Try the same legs as two separate searches. If the components are cheap and the construction is not, the construction is failing, not the route.
Dates out of order. The form expects legs in chronological sequence. An out-of-order date can produce empty or nonsensical results rather than an error message.
Prices that change when you click through. <cite index="11-1">Google notes that flight prices are updated approximately once every 24 hours</cite>. On a multi-leg itinerary there is more surface area for a stale price, and the number you see on the booking partner's site is the number that counts.
The itinerary disappears at checkout. Complex constructions fail at the partner site more often than simple ones, usually because the fare combination was available when Google cached it and is not available now.
Google Flights multi-city on mobile
The feature exists on the mobile web and in the Google app, with the same five-leg cap. The form is the same, stacked vertically.
Two differences worth knowing. Filters live behind a collapsed panel rather than a visible row, so it is easy to search without applying the bag filter you meant to apply. And a five-row form on a phone screen is genuinely tedious to correct, which makes the autofill-overwrite step in an open jaw an easy thing to get wrong. If you are building anything past two legs, build it on a laptop.
Honest verdict: is Google Flights multi-city worth using?
Google Flights multi-city is the best free tool for pricing a two-leg open jaw, and it is good enough for a three or four-leg run on a single alliance. The interface is clean, the five-leg ceiling is above what most trips need, and the breadth of partners means you are seeing a wide slice of what is bookable.
Where it thins out is exactly where complex trips get hard: no flexible-date tooling, no visibility into whether you are being shown one ticket or several until you look closely, and no way to price a mixed-cabin construction. Those are not small gaps on a four-figure international itinerary.
For a simple jaw, self-serve is fine. For a long chain across carriers, or anything with a premium cabin on one leg, the search box is a starting point rather than an answer.
Where a booking agent fits
Camli is a travel savings platform with access to consolidator fares, and our agents build these itineraries in a GDS every day. Two things a search box cannot do: check a construction against negotiated fares that are not published to metasearch, and put a complex multi-leg trip on a single ticket with one record locator so a delay on leg one is the airline's problem rather than yours. If your multi-city search came back higher than it should, or you need more than five legs, it is worth having someone price it both ways before you book. Sometimes the published fare wins and we will tell you so.
Frequently asked questions
How many flights can you add to a Google Flights multi-city search?
Five. Google Flights caps multi-city itineraries at five legs and there is no setting to raise it. If your trip needs more, the usual approach is to book the long-haul legs as one construction and buy the regional hops separately, or have an agent build it in a reservation system where the limits are different.
Can you book an open-jaw ticket on Google Flights?
Yes, and the multi-city tab is the only place to do it. Enter two legs: your home airport to your arrival city, then your departure city back to your home airport. Overwrite the autofilled departure city on the second row, since it defaults to your first leg's arrival city.
Why is my Google Flights multi-city search more expensive than a round trip?
Usually fare construction or fare-class availability. If the airline's system cannot assemble your legs into one fare it falls back on combining one-way fares, which carry a premium. Separately, the cheapest inventory buckets are not always open to multi-city construction, so the same flights can price from a higher bucket.
Can you track prices on a Google Flights multi-city search?
Price tracking, the price graph and the date grid are built around a single origin and destination, so a multi-leg itinerary has nothing for them to plot. The workaround is to track each leg separately as a one-way search and watch the components.
Does a multi-city result always mean one ticket?
No. Results can include combinations of separately ticketed flights, sometimes involving self-transfer of bags between them. Check whether one airline is ticketing the whole itinerary, and count the record locators on your confirmation. Several codes means several tickets, and a missed connection between them is not the airline's responsibility.
Can you book different cabins on different legs?
Not through the search form. The cabin selector applies to the whole itinerary. A mixed-cabin trip, business on the long-haul and economy on the short hops, needs either separate bookings or an agent-built construction.
Is multi-city cheaper than booking separate one-way tickets?
Often on international routes, because one-way fares carry a premium that constructed fares do not. Not reliably on short domestic routes or low-cost carriers, where one-ways are priced normally. Price it all three ways and compare totals with bags and ground transport included.
Does Google Flights sell multi-city tickets?
No. Google Flights is a metasearch engine. It shows offers from more than 300 airline and travel agency partners and sends you to one of them to pay. Whatever the search page showed, the partner's terms, fees and cancellation rules are the ones that apply to your ticket.
