AJX schedules nowadays (nights) are mostly back of the clock or night duties. AJX basically gets allocated flights by ANA, it does not have its own sales, marketing etc. It operates flights exclusively on behalf of ANA. ANA thus allocates flights to AJX and it's no surprise that these flights are pretty much the worst flights on the ANA international B767 network.
In happier days, before the merger and the management change which preceded it, we had admin managers who would not accept some of these flights, as these flights did not assist in decent fatigue management, so some flights were "easier" flights to allow for decent rest and overall reduction in fatigue.
Sadly, this seems to have fallen away now and the flights allocated appear to be accepted with no resistance form our office staff and management staff.
Rumor has it that a Delhi return will be on the schedule from October. 2 man crew, flight time around 10:35, departure around 6:30 pm, making that an arrival around 4:30 am Japan time. 25 hours off and an approx 8 hour flight back, also 2 man crew. NO crew rest, no heavy crew!! This in addition to some of the 6 or 7 day freighter flights, which have a mix of day and night flights, so a decent night's sleep in the 6 days is almost impossible.
Be prepared to be tired all the time, be flying crappy schedules while you are in Japan. The schedulers will try their luck and assign flights outside the accepted scheduling guidelines when things get tight, which is pretty much 24/7 nowadays.
There has been a steady stream of pilots leaving over the past 2 years, the majority stating that the fatiguing schedules were the main reason for their departure.
