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.
It will obviously change but its a pretty clear pattern so far. HKG was in extremis, and the MF crew stayed in separate hotels, as they did in ICN. That said the WW crews were very good with them.
