Direct or Connecting Flight? When a Layover Really Saves You Money
Are connecting flights always cheaper? We compared nonstop fares with all fares on 11 international routes, and found when a layover halves the price, when it saves nothing, and why a single ticket matters.
When you search for a flight, you'll often see two kinds of options: a nonstop flight at one price, and a flight with a stop somewhere else at a lower price. Is the layover worth the extra hours? And is it really cheaper, as people tend to assume?
We compared nonstop fares with all fares on 11 international routes, and put together what you need to know before choosing a connecting flight.
Are connecting flights really cheaper? What the numbers say
For each route, the table compares the cheapest fare among all flights, including those with a stop, with the cheapest fare among nonstop flights only, for the same route and month:
| Route | All flights | Nonstop only | Result |
|---|---|---|---|
| London → Istanbul | $159 | $159 | No difference |
| Paris → New York | $465 | $465 | No difference |
| New York → Miami | $178 | $178 | No difference |
| New York → Los Angeles | $254 | $254 | No difference |
| Istanbul → London | $151 | $163 | Connecting 7% cheaper |
| London → New York | $551 | $630 | Connecting 13% cheaper |
| London → Delhi | $600 | $700 | Connecting 14% cheaper |
| Madrid → New York | $301 | $419 | Connecting 28% cheaper |
| London → Bangkok | $560 | $1,118 | Connecting 50% cheaper |
| London → Dubai | $371 | $742 | Connecting 50% cheaper |
| Paris → Dubai | $283 | $784 | Connecting 64% cheaper |
How we got these numbers. They are the lowest round-trip fares in the TravelFlow price calendar for trips in January 2027 lasting 7 to 14 days, once for all flights and once for nonstop flights only, as recorded on November 2, 2026. "No difference" means the cheapest flight available was nonstop anyway. These prices come from recent searches by other travelers, so treat them as a guide to price levels, not guaranteed fares.
What do these numbers tell us?
- On short or very competitive routes, don't assume a stop is cheaper: on the first four routes, a connection saved nothing, so there's no reason to spend extra hours in another airport.
- On long-haul routes, the savings can be huge: from London to Bangkok or Dubai, the cheapest connecting option cost about half as much as the cheapest nonstop flight, a difference of $371 to $558 per ticket.
- The answer changes from month to month: from Paris to New York, both options cost the same in January, but in March the nonstop flight started at $598 against $498 with a stop.
- The rule: compare both options every time, without deciding in advance.
Compare for yourself: all flights vs nonstop
These two calendars show the same route, London to Dubai: the first shows the cheapest fare for all flights, the second for nonstop flights only. Compare the month that suits you in both, and change the cities in either calendar from its settings icon:

The key question: one ticket or separate tickets?
Not all connecting flights are equal. The most important question to ask before you book: are both flights on one ticket, or on two separate tickets sold together to look like one trip?
| One ticket | Separate tickets | |
|---|---|---|
| If the first flight is late and you miss the second | The airline usually rebooks you | The second airline isn't responsible, and you may need a new ticket |
| Bags | Usually checked through to your final destination | You collect them at the connecting airport and check them in again |
| At the airport | You usually stay airside | You may have to enter the country and go through security again |
| Visa | Often not needed | You may need an entry visa for the connecting country |
| Baggage allowance | Usually the same throughout | May differ between the two airlines |
When is a layover worth it?
- When the saving is big: as on London to Dubai, where a stop saved $371 per ticket.
- On very long journeys: a stop halfway through a long trip can be a welcome break, especially at a comfortable airport.
- When you'd like to see the connecting city: a long layover in a city like Istanbul, Dubai or Doha can become a short visit, if your visa allows you to enter.
- When there's no suitable nonstop flight: some routes don't have daily nonstop flights, or their schedules don't work for you.
When to choose the nonstop flight
- When the price difference is small: a few dollars isn't worth extra hours of waiting and the risk of a missed connection.
- When you're traveling with children or older relatives: every stop means extra effort and more airport procedures.
- When you're short on time: a business meeting or a family occasion can't absorb a delayed connection.
- When the tickets would be separate: if you can't find a connection on one ticket, the nonstop flight is usually the safer choice.
How long should your layover be?
There's no single number for every airport, but these are practical rules:
- On one ticket: airlines don't usually sell connections shorter than the airport's minimum connection time. Even so, we think 1.5 to 3 hours gives you a comfortable margin at most large airports.
- On separate tickets: we'd allow at least 4 hours, and more if you need to collect your bags, change terminals or go through passport control.
- On a very long layover: if it runs overnight, add the cost of a hotel and meals, which can eat up the whole saving.
Before you book a connecting flight
- Make sure both flights are on one ticket, or accept the risk knowingly if they're separate.
- Check visa rules for the connecting country: some countries require a transit visa for certain nationalities even if you don't leave the airport.
- Work out the total journey time from your door to your destination, not just the flying time.
- Compare baggage policies if the two flights are with different airlines.
- Find out whether you'll change terminals at the connecting airport, and how long the transfer takes.

Frequently asked questions
Are connecting flights always cheaper than nonstop flights?
No. On 4 of the 11 routes we compared, the cheapest flight available was nonstop anyway. But on long-haul routes the difference can be large. From London to Dubai, the cheapest connecting option was half the price of the cheapest nonstop flight.
What happens if my first flight is late and I miss my connection?
If both flights are on one ticket, the airline will usually rebook you on a later flight. If they are on separate tickets, the second airline isn't responsible for the first one's delay, and you may have to buy a new ticket.
Do I need a visa for a layover?
If you stay airside on a single ticket, you often don't, but some countries require a transit visa for certain nationalities even if you don't leave the airport. If you're on separate tickets and have to collect your bags, you'll usually enter the country and need its visa. Always check before you book.
How long should a layover be?
On a single ticket, we think 1.5 to 3 hours gives you a comfortable margin at most large airports. On separate tickets, we'd allow at least 4 hours, and more if you need to collect bags, change terminals or go through passport control.
How do I know if a connecting flight is on one ticket?
Read the itinerary details before you book. If there's a note that you need to collect and re-check your bags, or the two flights are with different airlines on separate bookings, they're most likely separate tickets. If in doubt, ask the seller before you pay.
