One-way tickets are no longer more expensive than half a return — budget carriers like Ryanair and easyJet price them identically. For immigration purposes, some countries require a return or onward ticket; check entry requirements before booking one-way international.
Tip: Mix airlines for one-way legs to get the cheapest total itinerary. Book each leg separately — often cheaper than one-way on a single carrier.
