AF also tried to pull the codeshare thing with me once. Didn't want to go around in circles with customer service and found it easier to initiate litigation. AF then hired a big law firm to defend the tiny case.

A week before a scheduled court hearing their lawyer calls me to negotiate. I tell her there is nothing to negotiate about, and she agrees. We chat for an hour anyway which was surely billed to her client AF. I receive full payment two days later.

Haven't booked an AF flight since.
