Multi-city or separate tickets? Complex trips from the US
Into Rome, home from Paris. Three cities in two weeks. Trips like these can be sold as a single ticket, and whether you book them that way or stitch separate tickets together decides who pays when a flight runs late.
If your trip has more than one stop, book it as one multi-city ticket unless you have a specific reason not to. On one ticket, the airline has to get you to the end of the itinerary when a delay breaks a connection, and your bags usually travel with you. On separate tickets, every flight is its own contract, and a missed second flight is yours to buy again. The rest of this guide covers what the terms mean, why the prices look odd, and the cases where that rule bends.
Three trip shapes and what they are called
A multi-city ticket is several flights sold as one itinerary: New York to London, London to Rome, Rome back to New York. You stay as long as you like in each place, and the whole trip carries one booking reference and one set of fare rules.
An open-jaw is the simplest version. You fly into one city and home from another, and cover the gap on the ground. Into Rome and home from Paris, with a train in between, is an open-jaw. So is leaving from New York and returning to Boston.
A stopover is a planned stay in the city where you would have changed planes anyway. The usual industry line is 24 hours on an international trip: under that it is a connection, over it is a stopover. On domestic US trips the line is typically four hours. Each airline writes its own stopover rules. Some allow one at no extra fare and some allow none, so it is a question to ask before you assume.
What one ticket buys you
The main thing is protection when something runs late. If your first flight is delayed and you miss the next one on the same ticket, the airline that sold you the connection has to put you on a later flight to your destination without charging a new fare. There is no argument between two companies about whose fault it was, because there is only one contract.
Bags are the second thing. On a connection inside one ticket, checked bags are normally tagged through to the next place you actually stop. One exception is worth knowing: arriving in the United States from abroad, you normally collect your bags at the first US airport, take them through customs and hand them back for the onward flight.
The third is that the connection has to be workable. Airports publish minimum connection times, and a single ticket is not sold below them. Separate tickets have no such check. Nothing stops you from buying a 50-minute connection of your own making in an airport where the published minimum is twice that.
One rule comes with the package. Flights on a ticket have to be flown in order. If you skip one, the airline will usually cancel everything after it, including the flight home. If plans change mid-trip, have the ticket changed rather than simply not turning up.
Where separate tickets still make sense
Separate tickets are not always wrong. They are reasonable when the gap between flights is measured in days, not hours. If you are spending four nights in Lisbon before a short flight to Madrid, that second flight is not a connection in any practical sense, and a separate one-way ticket is fine.
They are also sometimes the only option. Many low-cost carriers inside Europe and Asia do not sell through-tickets with long-haul airlines at all. If the only sensible flight for a short hop is on one of them, you will be on two tickets whether you planned to be or not.
When you do split a journey, plan as if the first flight will be late. Leave several hours, and leave overnight when the first leg is a long-haul. Expect to collect your bags, clear immigration and check in again from the public side of the airport. Read your travel insurance before relying on it, too: missed-connection cover on separate tickets often applies only after a minimum delay, and some policies exclude it altogether.
If the first flight is late and you miss the second, the second airline will generally record you as a no-show. A replacement seat is a new purchase at that day's price.
Why multi-city prices look strange
A multi-city ticket is priced as a whole, not as the sum of its one-way flights. That is why the total can come out lower than the one-ways added together on one search and higher on the next. Long-haul open-jaws often land close to the price of a regular round trip, because each direction is priced like half of one.
Order matters. The same three cities in a different sequence can produce a different total, because the long flights fall on different dates and different routes. The city you fly home from matters as well. It is worth pricing the trip both ways round before deciding where to start.
Ground travel can do some of the work. A two-hour train between two cities is often easier than a flight between them, and leaving that leg off the ticket turns a three-flight itinerary into a two-flight open-jaw.
Checks to make before you pay
Check airports, not just cities. London, Paris, Tokyo and New York each have more than one, and a connection that lands at one airport and leaves from another is a transfer you make yourself.
Check transit rules and passports. Some countries require a transit visa even if you never leave the airport, so confirm with the embassy or consulate of every country you pass through. Many countries also want a passport valid for months beyond your stay, and the strictest country on the itinerary sets the bar.
Check the names and the clock. The name on every flight has to match the passport exactly. Compare total journey time door to door, not flight time: an overnight connection can be the right call or a lost day, depending on the airport.
When to book it yourself and when to call
A two-stop trip on ordinary dates is something a multi-city search handles well, and you can price it online in a few minutes.
It is worth a phone call when the trip has three or more stops, when you want a better cabin on the overnight flight and economy on the short ones, when travelers are starting from different cities, when an infant or an assistance request is involved, or when the total simply looks wrong against the parts. An agent can price the same trip several ways while you are on the line and tell you which versions are on one ticket and which are not. That comparison is what our route comparison service is for.
