Find Cheap One-Way Flight Deals

Simply put, a one-way flight is a ticket that gets you to your destination without tying you to a return date. It’s ideal for travellers who value flexibility, whether you’re exploring indefinitely or staying for a while. Plus, it can be a cost-effective option if you don’t need a return trip.

Whether a one-way or return ticket is cheaper depends on several factors, including your destination, airline, and when you book. While return tickets were traditionally the go-to for savings, budget airlines and growing competition have made one-way options just as affordable in many cases. One-way tickets are often a better deal for short-haul or domestic flights, especially when flying with low-cost carriers. On the other hand, return tickets tend to be more budget-friendly for long-haul or international journeys. If you’re looking to save, consider a ‘hacker fare’, where you book two one-way tickets on different airlines.

Nearly all airlines provide one-way tickets, especially budget carriers that operate shorter routes. According to momondo users, Aer Lingus and Turkish Airlines are the most popular for one-way flights, making up 23% and 21% of bookings, respectively. It’s worth noting that some international destinations may require proof of onward travel due to visa regulations, which airlines often need to check. Always confirm these rules when booking one-way tickets abroad.

It’s possible to score budget-friendly one-way flights to international destinations. momondo data from the past two weeks shows that Dublin to Birmingham for €24, Dublin to Newcastle upon Tyne for €24, and Dublin to Liverpool for €30 are some of the top deals.
