Cheap One Way Flights
Looking for cheap one way flights? You're in the right place. CheapOair searches one way airline tickets across 500+ airlines in seconds — so whether you're flying domestic or heading overseas, you see the lowest available fares upfront, with taxes and fees included.
What Is a One Way Flight?
A one way flight is exactly what it sounds like — a ticket that gets you from point A to point B, with no return leg attached. You pay for the journey you actually need, nothing more.
That simplicity makes one way tickets genuinely useful in a lot of situations — not just when you're unsure of your return date. One way airline tickets have become far more competitively priced in recent years, especially on domestic US routes, thanks to budget carriers and increased airline competition.
Who Books One Way Airline Tickets?
Travelers booking one way flights typically fall into a few categories:
- People relocating to a new city or country and not planning to come back
- Multi-city travelers flying into one destination and out of another
- Business travelers with open-ended stays
- Backpackers and long-term travelers who want flexibility on when they move on
- Travelers combining two one way tickets on different airlines to beat the round trip price
When Does a One Way Ticket Make More Sense Than a Round Trip?
Round trips are usually cheaper — but not always. Here's when one way tickets are worth looking at:
- You're doing a multi-city trip (fly into Chicago, fly home from Miami — book each leg separately)
- The round trip prices out higher than two separate one ways on budget carriers
- Your schedule is open-ended and locking in a return date would cost you in change fees
- You want to mix airlines — fly out on Delta, return on Southwest — to get a better combined price
For short domestic routes, the math often favors one way. For long-haul international, round trips are usually still the better deal — but it's worth checking both.
How to Find the Cheapest One Way Flights
There's no magic to finding low fare one way flights — it's mostly about timing, flexibility, and knowing where to look. Here are the tactics that actually work:
1. Search on Tuesday or Wednesday
As per historical data, Tuesday and Wednesday are the two best days to search for cheap one way tickets. Flying mid-week (instead of Friday or Sunday) also tends to be cheaper on most domestic routes. (Based on cheapoair’s historical data)
2. Use the Flexible Date Calendar
If your travel dates aren't locked in, CheapOair's flexible date search shows you the cheapest day to fly across the full month on your route. A shift of even one or two days can cut the fare on some routes — especially popular leisure routes like New York to Miami or Chicago to Las Vegas.
3. Compare Nearby Airports
Flying from New York? Compare JFK, EWR, and LGA. The cheapest one way flight out of a metro area may depart from a secondary airport, and the price difference can sometimes be significant on a single segment. CheapOair searches all nearby airports at once.
4. Consider Connecting Flights vs. Nonstop
Cheap one way nonstop flights are great if you can find them. But connecting flights are often significantly cheaper. If your schedule allows an extra couple of hours, filtering for 1-stop options regularly surfaces the lower one way fares on any given route.
5. Book at the Right Time
For domestic one way flights, the sweet spot is 1–3 weeks before departure. Book too far in advance and fares are often still high. Book within 3–5 days and you're at the mercy of last-minute pricing. That said, last minute one way flights do exist — high-frequency routes like LAX to LAS or JFK to MCO sometimes have genuinely cheap seats available within a week.
6. Set a Price Alert
Not ready to book yet? Set a free price alert on CheapOair for your route and we'll notify you when the fare drops to your target price. Takes 30 seconds to set up.
7. Bundle with a Hotel for Extra Savings
Booking a one way flight and hotel together on CheapOair typically gives a better value versus booking each separately. If you're heading somewhere new and need a place to stay, the package option is worth checking.
One Way vs. Round Trip — When One Way Actually Wins
The old rule was simple: round trips are always cheaper. That's mostly still true for long-haul international flights. But on domestic routes, it's no longer a given.
Budget airlines have made domestic one way pricing genuinely competitive. On routes with strong budget carrier presence — LAX to LAS, ORD to MCO, JFK to FLL — one way ticket prices can sometimes match or beat half the round trip price. Factor in a different return route and the one way option often wins outright.
For international routes, booking two one ways internationally rarely saves money compared to a single round trip — unless you're combining two budget international carriers, or your routing in and out is through different cities.
The cleanest way to check is to run both searches on CheapOair: enter your route as one way first, note the price, then switch to round trip and halve it. If the one way costs less than half the round trip — one way wins. If it's more — go round trip.

Frequently Asked Questions About One Way Flights
What is a one way flight?
A one way flight is a ticket that covers travel from your departure airport to your destination with no return leg included. Unlike a round trip, which locks in both the outbound and return journey in a single booking, a one way ticket gives you the freedom to decide your return plans separately — or not at all. One way fly tickets are commonly booked by travelers relocating, doing multi-city trips, or simply keeping their itinerary flexible.
How much does a one way ticket cost?
One way ticket prices vary by route, airline, and how far in advance you book.
Is it cheaper to buy one way or round trip?
For domestic flights, it depends on the route and airline. Budget carriers like Frontier and Southwest have made domestic one way pricing very competitive — sometimes the total of two one ways beats the round trip price, especially when mixing airlines. For international flights, round trips are usually better value on legacy carriers. The quickest way to check is to search both options on CheapOair: run a one way search, then a round trip, and compare the total cost.
What is the cheapest day to book a one way flight?
Based on historical data, Tuesday and Wednesday are generally the cheapest days to search for and book one way airline tickets. Airlines release sales on Monday night and competing carriers typically match those prices by Tuesday morning. Flying on a Tuesday, Wednesday, or Thursday is also cheaper than weekend travel on most domestic routes — mid-week departure days can reduce one way fares on popular routes.
How far in advance should I book a one way flight?
For domestic one way flights, booking 1–3 weeks before departure tends to offer the best combination of availability and price. Going much further out, fares are often still high. For one way international flights, aim for 2–6 months in advance, especially for transatlantic or transpacific routes where inventory is more limited. Last minute one way flights are possible on high-frequency domestic routes within a week of departure, but pricing becomes unpredictable.
Can I find cheap one way non-stop flights?
Yes. Cheap one way non-stop flights exist on most major US domestic routes — particularly between major hubs like New York, Los Angeles, Chicago, Miami, and Las Vegas. Use the "nonstop only" filter on CheapOair to see all available nonstop one way options on your route. Nonstop one ways are usually priced slightly higher than connecting fares on the same route, but not always — especially on routes where budget carriers fly direct.
How do I find the cheapest one way airline tickets?
To find our lowest one way flights on CheapOair: select "One Way" on the search form, enter your route and date, then sort results by price. Use the flexible date calendar if your dates aren't fixed — it shows the cheapest day to fly across the whole month. Compare nearby airports (especially in New York, Chicago, and Los Angeles where multiple airports serve the same metro area). Setting a price alert is also effective if you're not ready to book immediately.
Are one way international flights more expensive?
Historically, yes — many full-service carriers priced one way international tickets close to the full round trip cost, making two separate one ways a poor deal. This has shifted with increased competition, particularly on short-haul international routes like US to Mexico, US to Canada, and US to Caribbean. On these routes, one way international fares are now reasonably competitive. For long-haul routes (US to Europe, US to Asia), round trips are still typically better value. CheapOair shows both options so you can compare directly.
Can I book a last minute one way flight?
Yes. Last minute one way flights are available on CheapOair across 500+ airlines. The best availability for last-minute deals is on high-frequency domestic routes — routes like New York to Fort Lauderdale, Los Angeles to Las Vegas, and Chicago to Orlando regularly have available one way seats within a few days of departure. International last minute one way flights exist too, though availability and pricing are less predictable. Use the "Last Minute" filter or browse CheapOair's last minute flight deals.
Can I earn rewards on one way flight bookings?
Yes. CheapOair's ClubMiles program lets you earn reward points on every one way ticket booking. Points can be used to get better deals on future bookings. Stack ClubMiles points with your airline's frequent flyer miles for double rewards — your airline miles still accrue normally when booking through CheapOair. Join ClubMiles for free before you book.
