I very much doubt that M/F are not getting routes that have more than a single service because the WW crew will turn on them. What a horrid assumption!
I'm afraid in this case its true. I heard it direct from the mouth of someone very very involved in the setting up of mixed fleet. Partly as a result of several nasty incidents when non strikers arrived in hotels during the strike last year.
Not true. Had a chat with a BA system developer the other day. It's a technical issue with certain systems, causing problems because of the different ranks and rules structures of Mixed Fleet.
