A large amount of codeshares which should be listed on oneworld timetables and in the booking tool, aren't.
I contacted oneworld web support about it (again) and they finally responded:
Please send us the example of the route you mentioned, so we can investigate and get back to you with a reply.
I've noticed AA coded QR operated flights (all of them) and AA coded MH operated LHR-KUL.
Has anyone seen anything else that I can send them?
