Cheap Round Trip Flights — Compare Round Trip Airfare Deals
Looking for cheap round trip flights? Compare fares for your departure and return dates in one search to find round trip airfare deals that fit your trip and budget. CheapOair makes it easy to compare flight options from 500+ airlines, including domestic and international routes, so you can choose the itinerary that works best for you.
A round trip flight includes travel from your origin to your destination and a return flight back to your starting point. For travelers with set departure and return dates, booking both flights together can be convenient and, depending on the route and airline, may cost less than purchasing two separate one-way tickets.
Why Book Round Trip Flights Instead of One Way?
Round trip flights can be cheaper and more convenient than booking two separate one-way tickets, but the best option depends on your route, airline, dates, and fare availability.
When you book a round trip, you can compare your outbound and return flights together and manage the itinerary under one booking. This can make planning easier for vacations, business trips, family visits, weekend getaways, and other journeys with a fixed return date.
However, booking two one-way flights can sometimes offer better value. This may happen when different airlines have lower fares for each direction or when your travel plans are flexible.
Before booking, compare both options to see which combination offers the best overall price, schedule, and flexibility.

How to Find Cheap Round Trip Flights
Finding a lower round trip airfare often comes down to comparing more options and being flexible when your travel plans allow it.
1. Compare flexible travel dates
If your schedule allows, check different departure and return dates. Moving your trip by a day or two can sometimes reveal lower fares, particularly around busy weekends and holidays.
2. Compare nearby airports
Your departure or arrival airport can make a significant difference to the total fare. If you have access to multiple airports, compare them before booking.
3. Consider different departure times
Early-morning, late-evening, and red-eye flights can sometimes have lower fares than flights during the busiest travel periods. If you don't mind traveling overnight, compare red-eye flights as part of your search.
4. Compare airlines and flight combinations
Don't assume the same airline will have the lowest fare in both directions. Compare available flight combinations to find an itinerary that balances price, travel time, stops, and convenience.
5. Travel outside peak periods
Airfares can increase when demand is high. School holidays, major events, summer travel, Thanksgiving, Christmas, and New Year's are often busy travel periods. If possible, consider traveling before or after the busiest dates.
6. Consider booking your hotel with your flight
If you also need accommodation, compare flight and hotel options together. A package may offer savings compared with booking each component separately, depending on the trip and available offers.
7. Check last-minute fares
Planning a trip soon? Compare available last minute flight deals, but don't assume waiting until the last minute will always result in a lower price. Fares can increase when seats become limited.
8. Consider your total travel cost
The cheapest advertised fare isn't necessarily the cheapest trip. Check baggage allowances, seat selection, change and cancellation rules, connection times, and other applicable fees before choosing your flight.
When Is the Best Time to Book Round Trip Flights?
There is no single best day or booking window that guarantees the lowest airfare for every route.
Flight prices change based on factors such as demand, seasonality, route, airline availability, travel dates, and remaining seats. Instead of relying on one specific day to book, compare fares regularly and look at different travel dates when possible.
For many travelers, planning ahead can provide more choices, particularly for international trips and travel during busy seasons. However, the ideal booking window varies by destination.
Planning a domestic round trip?
Compare fares several weeks or months before your departure date and continue checking if your plans are flexible.
Planning an international round trip?
Start comparing fares well ahead of your trip, particularly if you're traveling during summer, holidays, or other peak periods.
Traveling during a peak season?
Book earlier when possible. Popular routes can have fewer affordable seats available as the travel date approaches.
Tip: Instead of focusing only on when you book, also compare when you fly. Changing your departure or return date can have a bigger impact on the final fare.

Cheap Round Trip Flights FAQs
Are round trip flights cheaper than one way?
Round trip flights can be cheaper than buying two separate one-way tickets, but it depends on the airline, route, dates, and available fares. Compare a round trip itinerary with two one-way flights before booking to find the best overall value.
What is the cheapest day to book round trip flights?
There is no universal cheapest day to book a flight. Airfares change frequently based on demand, availability, route, season, and other factors. Compare prices across different days and travel dates rather than relying on a single day of the week.
What are the cheapest days to fly round trip?
Midweek and less busy travel days can sometimes have lower fares than peak travel days, but there is no guaranteed cheapest day for every route. Compare several departure and return dates to identify lower available fares.
How far in advance should I book round trip flights?
The best time to book depends on your destination, travel season, airline, and dates. Start comparing fares early, especially for international trips and peak-season travel. If your dates are flexible, continue comparing different travel dates to find the best available fare.
Can I book a round trip flight with two different airlines?
Yes, some round trip itineraries can include different airlines for the outbound and return flights. When available, compare these combinations with single-airline itineraries and consider the total price, baggage rules, schedules, and connection requirements.
Do round trip flights have to return to the same city?
A traditional round trip normally returns you to your original departure city. However, you can also consider an open-jaw or multi-city itinerary when you want to return from a different city.
What is an open-jaw round trip ticket?
An open-jaw itinerary is a type of round trip where the origin or destination differs on one portion of the journey. For example, you could fly from New York to Rome and return from Paris to New York. This can be useful when visiting multiple cities during one trip.
Is it cheaper to book round trip or two one-way tickets?
Neither option is always cheaper. A round trip may offer a lower combined fare, while two one-way tickets can sometimes be less expensive when different airlines offer better prices in each direction. Compare both options before booking.
What is the cheapest month to fly round trip?
There is no single cheapest month for every destination. Airfare varies by route and season. Traveling during lower-demand periods can sometimes provide better fares than peak summer, holiday, or event periods.
Can I change or cancel a round trip flight?
Change and cancellation options depend on your airline and fare rules. Before purchasing, review the ticket's change, cancellation, refund, and credit conditions. Some fares may be non-refundable or may involve fees or fare differences when changed.
Can I take a one-day round trip flight?
Yes. Same-day round trips are possible on many routes, particularly shorter domestic routes with multiple daily flights. Look for an early departure and a later return if you want to maximize your time at the destination.
How do I find the lowest round trip airfare on CheapOair?
Enter your departure city, destination, and travel dates into the CheapOair flight search tool. Compare available round trip fares, airlines, schedules, cabin options, and applicable fare conditions. If your dates are flexible, search different combinations to find additional options.
Are round trip tickets refundable?
Refundability depends on the airline, fare type, and ticket rules. Check the fare conditions before completing your purchase to understand whether your ticket can be refunded, changed, or canceled.
Can I change only one flight on a round trip ticket?
It may be possible to change only the outbound or return portion of a round trip itinerary, depending on the ticket's fare rules and airline policy. Check the conditions of your specific booking before making changes.
What is included in a round trip flight ticket?
A round trip ticket generally covers transportation from your departure point to your destination and a return journey. Baggage, seat selection, meals, changes, and other services may or may not be included depending on the airline and fare type.
Are round trip flights better for vacations?
Round trip flights can be convenient for vacations when you know your departure and return dates. Booking both journeys together makes it easier to compare the complete itinerary and manage your trip. However, travelers with flexible plans should also compare one-way and multi-city options.
