I posted this down thread: E.g. LAX-NRT on 3/2 on UA 32 is $966 right now. Add a return flight on 3/9 and the flight _drops_ to $893.

Happens all the time on Air Canada and Air France between Toronto and Paris.

Round-trip: $800

One-way: $2000 (or $4k for two one-ways to make up a round-trip)

I don’t know why anyone would ever book a one-way. It’s insanity.

It’s a real pain, and makes it harder to create your own open-jaw when the airline doesn’t serve all 3 cities.

What ends up happening is I book through other airlines entirely that don’t pull these shenanigans.

As part of her bachelor degree my SO spent 3 months in one of the west-African countries. On the way back, they wanted to meet up in South-Africa with some other students who had gone to a different country for a vacation before returning home.

Since she hates stuff like this, I was tasked with finding a cheap tickets. For the first trip from here in Norway to the west-African country, I found that the cheapest tickets were from KLM (who flew direct from Amsterdam, so only one stop), and the round-trip ticket was indeed about $300 cheaper than a one-way ticket.

This is true for domestic flights, but international round trip tends to be cheaper
