So, I have a flight that I booked through American, but is operated by Alaska. I'm now looking to change it (ideally through Alaska, as the flight is 62 days from now and they apparently don't charge a change fee outside 60 days). However, Alaska seems to only allow changes for flights booked through them, while American only allows changes for flights on their own planes.
My question is, is it possible to get this changed, and if so, which airline should I call to change it?
