One round-trip ticket, or two one-ways?
Airlines don't price a return as two halves. Sometimes the round trip carries a huge discount; sometimes two separate one-ways — even on two different airlines — come out cheaper. Here we compare both with live prices and tell you which wins. It's usually the simple one.
Start a search to compare: we need an origin, a destination and both dates.
Why the difference exists
A fare isn't the cost of moving the aircraft — it's what the airline believes it can charge you. A round trip guarantees them both legs, so they often reward it with a price that simply doesn't exist if you buy the outbound alone.
On long routes that discount is usually enormous and splitting the trip is clearly worse. On short routes, especially those flown by low-cost carriers, every leg is priced separately anyway — and there, building the trip from two tickets, sometimes on two airlines, can genuinely win.
There is no rule that always holds. That is why this is a live comparison and not advice.

When each one wins
Long and intercontinental flights, itineraries with connections, any trip where a delay is expensive. One purchase, one booking, and one airline responsible for the whole journey.
Short hops, routes dominated by low-cost carriers, and trips where the outbound and return face very different demand. It saves when it saves, but it leaves you without a safety net.
What to understand before splitting a trip in two
- These are two separate purchases on two different sites. You have to complete both. If you buy one and the other rises or sells out meanwhile, you own half a trip.
- The two airlines have no relationship. If your outbound is cancelled, the return airline owes you nothing — no rebooking, no refund of the other ticket. On a single ticket, that problem belongs to the airline, not to you.
- Baggage is not checked through and each ticket carries its own allowance. Two bags, two fees.
- If the saving is under 2%, don't. Any baggage fee or exchange-rate move swallows it, and you're paying that in trip risk.
