What are one-way flights?
A one-way flight is a ticket that takes you to a destination without including a return journey.
There are lots of reasons travellers choose to book one-way flights:
- Moving abroad – Relocating to a new country? One-way tickets are the obvious choice.
- Flexible travel – Backpacking, slow travel, or remote work? A one-way flight lets you plan as you go.
- Uncertain return dates – Sometimes you just don’t know when you’ll be back.
- Open-jaw or multi-city trips – If you’re flying into one destination and out of another, one-way tickets are ideal.
💡 For example: A backpacker might fly one-way from London to Bali, then later book separate flights around Southeast Asia once they confirm their itinerary.
Are one-way flights cheaper than a round trip?
Not always - but sometimes they can be, especially when you're mixing airlines or booking flexible routes.
Depending on your travel dates and airlines, two one-way flights can often save you money, especially when booking with budget airlines or flying at off-peak times.
💡 That’s why it’s important to compare both options. With Alternative Airlines, you can easily search, compare, and build the most cost-effective itinerary using our Best Fare Finder flight search tool.
Use filters to sort by cheapest price, airline, stopovers, and flexible ticket options, so you always find the best deal for your one-way or round-trip flights.

Tips for finding cheap one-way flights
Want to keep costs low? Here are some things to keep in mind:
Be flexible with your travel dates
Fares fluctuate depending on the day of the week and time of year. Flying mid-week is often cheaper than weekends, when demand is higher. Avoid school holidays, major events, and peak travel periods if you’re looking for lower fares. If your dates are flexible, use our Best Fare Finder tool to view prices across different days.
Check for last-minute flight deals
If you’re not tied to a specific plan, booking a one-way flight at the last minute can sometimes lead to discounts. Airlines often lower fares on unsold seats close to the departure date to fill the plane. Keep an eye on our last-minute one-way flights guide and use our filters to sort by the cheapest available fares.
Compare multiple airlines for your route
Don’t just look at one airline as prices can vary widely for the same route. With Alternative Airlines, you can compare flights from over 600 airlines, including premium and ultra-low-cost options. For example, flying from London to Madrid might be more affordable on a budget airline like Ryanair or easyJet, compared to a full-service carrier like Emirates.
Use budget airlines where available
Low-cost carriers are a great way to save money on one-way flights, especially for short-haul routes. Airlines like Spirit, Frontier, Wizz Air, AirAsia and Scoot often offer significantly lower base fares than traditional airlines. Just be aware of extra fees for baggage, seat selection and onboard services—and factor those into your total cost.
Mix and match airlines
Instead of booking a return flight with one airline, try combining two one-way tickets with different carriers. This not only opens up more options but can often lead to savings, especially on international routes. For example, you could fly from New York to Paris with JetBlue and return with French Bee, potentially saving money while also choosing more convenient times.
Use buy now, pay later
Even if you don’t find a low fare, you can still manage your budget by using a buy now, pay later option. At Alternative Airlines, we offer flexible payment plans through providers like Klarna, Afterpay, Affirm and PayPal Credit. These let you spread the cost of your flight over weekly or monthly instalments, which is ideal if you’re booking on short notice or need more time to budget.
