Thankyou Betty Girl but I do in fact know BA and what goes on rather well.
BA's cabin crew rest periods are generally way above CAA requirements and are configured in such a way- ie occupying all but the first couple and last of hours of long haul flights,- that mid flight meals are not possible,notably in World Traveller.Too often "To Fly to Rest" seems to be the guiding principle, and what I say about the resultant difficulties with 12 hour plus daylight flights are as I describe.
Another nonsense you will be familiar with on short haul is the refusal to treat a transit through Heathrow just like any other aiport and to require minimum layover times there which make it impossible to roster short haul aircraft, pilots and cabin crew to operate through it and stay together through the day's work. All 3 are rostered separately which results in massive disruption and cancellations once bad weather or whatever interrupts the schedules.The earlier in the day the problem occurs the greater the damage. The extended cabin crew LHR transist also mean that 4 sector days become impossible, thus generating more night stops=more crew=higher costs. One result is that other than as a feeder to long haul BA can not make money on nearly all of short haul despite the massive investment in aircraft etc it requires and would be well shot of it."Go" was probably the answer, failing which franchises which provided a BA branded operation at no cost to BA.
