A round-trip flight is when you fly from somewhere and then return to that original location.
When you book a round-trip flight, you receive a single ticket that covers both the outbound and inbound legs of the journey.
Round-trip flights are usually cheaper than booking multiple one-way flights, especially for international destinations.
But you sacrifice flexibility and have to pay more upfront for a round-trip ticket.
Rescheduling round-trip flights can also be both difficult and expensive.
What is a Round Trip Flight?
A round-trip flight is when you purchase tickets for a flight to a destination and then back to your original location.
For example, you could book a round-trip flight from London to New York City and then back to London from New York City.
How Do Round Trip Flights Work?
A round-trip flight includes a flight from your original location, let’s call ‘A,’ to your destination, let’s call ‘B,’ as well as a flight from B back to A.
With a round-trip ticket, you get a flight to B, where you’ll stay for as long as you like before going back to A.
Round-trip flights are the most popular flights for travelers who are flying for a vacation.
Are Round Trip or One Way Flights Cheaper?
Round trips are almost always cheaper than one-way flights when booking with the same airline, with most airlines incentivizing round trips, especially for leisure travel, and especially to international destinations.
- A round trip from London to New York may cost $1,000.
- A one-way trip to New York City from London might cost $600, and a one-way trip from London to New York City may also cost $600.
- In this example, you’d save $200 by choosing a round trip with the same airline rather than booking two separate flights.
But it could be cheaper for you to fly with two different airlines.
Let’s say you find a British Airways flight from London to New York City for $600. But you also find a Delta Air Lines flight from New York City to London for only $300.
In that case, you’d save $100 by buying two one-way flights from different airlines.
Do You Have to Fly Both Legs of a Round Trip Flight?
You’re not technically obligated to fly both legs of a round-trip flight.
If you fly the first leg from your location to the destination, you could stay there longer and miss the return flight if you wanted to.
But airlines dislike this behavior and may penalize your flying privileges if you do this repeatedly.
If you miss the first leg of your round-trip flight, the airline will most likely automatically cancel the return flight, too.
How Long Can You Stay on a Round Trip Ticket?
You can stay on a round-trip flight for as little as one day to as long as a year.
The exact duration you can stay depends on the airline’s booking policies and flight availability.
Pros of Round Trip Flights
1. Lower Costs
Round trips from the same airlines are almost always cheaper than booking two one-way flights.
Round trips for international flights are especially cheaper than purchasing two one-way tickets from the same airline.
2. Lower Taxes
You only have to pay sales tax once with a round-trip flight.
That’s because you only have to pay for one ticket, which includes both your flights.
3. Fewer Cancellation Fees
You’ll only be charged a single cancellation fee if you cancel a round-trip flight.
But if you cancel two one-way flights, you’ll pay cancellation fees for both flights.
You can save a lot of money on round-trip flights if you have a voucher, like a companion voucher from a credit card.
You’ll save more when booking round-trip flights, since an individual round-trip flight costs more than an individual one-way flight.
And vouchers can only be used once and are usually a percentage discount.
Cons of Round Trip Flights
1. Changing the date can be more expensive
Changing the dates for a round-trip flight costs between $0 to $400.
In some cases, it could be so expensive that you’d be better off missing a flight and booking a new one-way flight instead.
2. Expensive domestic flights
Round-trip domestic flights with the same airline could be more expensive than booking multiple one-way domestic flights with different airlines.
Most airlines are more price competitive for domestic routes rather than international ones.
3. High Upfront Costs
You have to pay more up-front for a round-trip flight than when booking a one way flight.
4. Automatic Itinerary Cancellations
If you miss the first leg of your round trip, the airline may also cancel your return trip, and you will lose your money.
5. Decreased Flexibility
You have to meet the scheduled flight date and times for a round trip flight.
Whereas with multiple one-way trips, you could just book your return flight whenever you want while at your destination.
You can technically change your return flight for a round-trip, but it’s often expensive and difficult.
What is a One-Way Flight?
A one-way flight is a flight from one destination to another destination that doesn’t include a return flight.
What is an Open-Jaw Flight?
An open-jaw flight is when you travel from your location to a first destination.
Then you travel to a different subsequent destination(s) and return to your original location from one of the subsequent destinations.
For example, you could fly from New York to Paris. Then drive from Paris to Berlin and fly from Berlin back to New York.
