This has been going on for years, I had a worse experience. I book my christmas flights super early and had to change the outgoing flight. Found a reasonable flight on a different airline, so all i wanted to do is cancel the outgoing portion of the flight. Having been burned by a similar experience to yours in the past, so knew I had to call the airline. Website says its not possible so I call them up. Apparently they cant cancel half the flight, they have to cancel and rebook, minus change fee, plus the difference in fare - insane due to it now being close to christmas. I ended up paying money to cancel half of my flight.
