An old idea, but one I had nearly forgotten over the past few years with the way most airlines now price seats...

I need a one way flight from Nairobi to Addis at a specific time in October. It was pricing at US$536.

I tried a round trip ticket, with a return a week later and the RT was only US$194!

I'll just discard the return and doubt they'll catch it. I guess I might lose 700 MQMs if they do. I'm surprised at the large disparity between fares and thought this was largely a thing of the past.
