How can any airline management not think safety is compromised by this sort of rostering.
Captain gets a new F/O, so presumably has to brief said worthy re a/c tech state, fuel state, WX etc etc etc. At the same time keep an eye on the turnround, slot, developing WX, De-iceing (and other winter operating factors)
Cabin crew changes. Presumably they have to brief each other on any peculiarities on the aircraft cabin also. This with all the other attendant problems of turnround plus get their pax off, get to a new aeroplane, get pax on etc. All in 25 mins? I don't think so!!
Not a good idea, definately a "bean counter" concept and not conducive to safety.
