Booking a flight for your next vacation or trip home? You’ll likely encounter the term “roundtrip flight” when searching for airfare. Knowing what a roundtrip flight entails and how it differs from other flight types can help you find and compare the best flight options.

If you’re short on time, here’s the quick answer: A roundtrip flight means you will depart from one city and arrive in another, then return back to the original departure city on a single itinerary. It’s the most common flight booking for travelers.

In this in-depth guide, we’ll explain everything that goes into a roundtrip flight including the definition, how it works, benefits, what to look for when booking, and how it compares to one-way and multi-city flights.

What is a Roundtrip Flight?

A roundtrip flight refers to a type of air travel where a passenger purchases a ticket for a journey from one destination to another and then back to the original starting point. This means that the flight itinerary consists of two legs: the outbound flight and the return flight.

The Basic Definition

A roundtrip flight is often the most common choice for travelers who have a specific destination in mind and plan to return to their starting point. It offers the convenience of booking both the outbound and return flights at the same time, usually with the same airline or through a travel agency.

This type of ticket is commonly used for vacations, business trips, and other travel purposes.

How a Roundtrip Flight Works

When booking a roundtrip flight, travelers typically select their departure date and time, as well as the return date and time, all in one transaction. The airline or travel agency will provide the passenger with a single ticket that includes both flights.

This ticket will usually have a unique confirmation code or booking reference number that should be kept safe for future reference.

Upon arrival at the airport, passengers need to check in for both the outbound and return flights. It is important to arrive at the airport with enough time to go through security and complete the check-in process for both legs of the journey.

Comparing Roundtrip vs One-Way vs Multi-City

When planning air travel, it is essential to understand the differences between roundtrip, one-way, and multi-city flights.

One-way flights: These flights are designed for travelers who do not plan on returning to their starting point. They are suitable for those who have a one-way journey or have separate return travel arrangements.

One-way flights can be more expensive than roundtrip flights, depending on the destination and availability.

Multi-city flights: Also known as open-jaw flights, multi-city flights allow travelers to visit multiple destinations on a single ticket. For example, a traveler may fly from New York to London, then Paris to New York.

Multi-city flights offer flexibility and convenience for those who wish to explore different locations without having to purchase separate one-way tickets.

Comparing Roundtrip vs One-Way vs Multi-City:

Flight Type Advantages Disadvantages
Roundtrip – Typically cheaper than two separate one-way tickets
– Convenient for travelers returning to the starting point
– Limited flexibility for changing travel plans
– Not suitable for those with one-way itineraries

Understanding the differences between these flight types allows travelers to make informed decisions based on their specific travel needs and preferences.

Benefits and Drawbacks of Booking Roundtrip

Potentially Cheaper Overall Cost

One of the major benefits of booking a round trip flight is that it can often be cheaper in terms of overall cost. Airlines typically offer discounted fares for round trip bookings as compared to booking two separate one-way flights.

This is because airlines want to encourage travelers to book both legs of their journey with them. By bundling the flights together, airlines can fill up their planes more efficiently, resulting in cost savings that are passed on to the passengers.

So, if you have a fixed travel schedule and know your return date, booking a round trip flight can save you money.

Simpler Logistics

Booking a round trip flight also simplifies the logistics of your travel. With a round trip booking, you don’t have to worry about separately booking your outbound and return flights. This can save you time and effort in searching for flights, comparing prices, and making multiple reservations.

Additionally, having a round trip ticket means you have a confirmed seat on both legs of your journey, providing peace of mind and avoiding the stress of last-minute flight availability.

Possible Limitations on Length of Stay

One drawback of booking a round trip flight is that it may come with limitations on the length of your stay at your destination. Some airlines and fare classes have restrictions on how long you can stay at your destination before returning.

These restrictions can vary depending on the airline and the specific fare rules. Therefore, if you want the flexibility to stay at your destination for an extended period, a round trip flight might not be the best option for you.

Can be Less Flexible

Another drawback of booking a round trip flight is that it can be less flexible compared to booking separate one-way flights. If your travel plans change or you need to alter your return date, you may have to pay change fees or even purchase a new ticket altogether.

This lack of flexibility can be a disadvantage for those who prefer to have more control over their travel plans. However, it’s worth noting that some airlines offer more flexible round trip fares with options for date changes or refunds, although these may come at a higher price.

What to Look for When Booking a Roundtrip Flight

Departure and Return Dates

When booking a roundtrip flight, it is important to carefully consider the departure and return dates. Make sure you choose dates that work well with your schedule and allow you enough time at your destination.

It is also worth checking if there are any major holidays or events happening during your intended travel dates, as this could affect prices and availability.

Number of Layovers and Stops

Another important factor to consider when booking a roundtrip flight is the number of layovers and stops involved. Some travelers prefer direct flights to minimize travel time, while others don’t mind layovers if it means getting a better deal.

Consider your personal preferences and priorities when deciding which option is best for you. Keep in mind that layovers can sometimes add extra stress and potential delays to your journey.

Baggage Allowance and Fees

Before booking a roundtrip flight, it is crucial to check the baggage allowance and fees of the airline you are considering. Different airlines have different policies regarding the number and weight of bags allowed, as well as any additional charges for exceeding the limits.

Be aware of these policies to avoid any unexpected surprises or extra costs during your trip.

Cancellation and Change Policies

Lastly, it is always wise to familiarize yourself with the cancellation and change policies of the airline you are booking with. Life can be unpredictable, and circumstances may arise that require you to modify or cancel your travel plans.

Knowing the airline’s policies beforehand can save you from unnecessary stress and potential financial loss. Some airlines offer flexible options, while others may have stricter policies.

Remember that each airline may have its own unique set of rules and regulations, so it is important to read the fine print and understand the terms and conditions before making a final decision. By considering these factors and doing your research, you can ensure a smoother and more enjoyable roundtrip flight experience.


When planning any kind of trip involving air travel, understanding the difference between roundtrip, one-way and multi-city flights allows you to choose the best option for your needs. Roundtrip flights involve departing from and returning to the same city on a single itinerary and are the most common booking for many travelers thanks to potential cost savings, simpler logistics and ease of comparison.

Be sure to consider optimal departure and return dates, layovers, baggage policies and change/cancellation fees when booking your next roundtrip flight.
