I just booked a flight with 2 segments using CO and CM. On my CO segment I am getting a L fare class but for my CM segment I am getting a fare class "O" as First (which it's BF for CM). I have never heard of such a fare class. I looked up on CO.com and they consider this fare class a full discounted economy if I were to use CO metal. Does anyone know what type of EQM will I get for this fare class? Thanks!
