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:
💡 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.
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.

Want to keep costs low? Here are some things to keep in mind:
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.
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.
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.
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.
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.
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.
