Wondering why Boeing would not simply utilise the APU to run BOTH packs and therefore air conditioning in front AND back cabins. APU Air is good up to what... FL220? Simply use APU to power both packs and maybe turn off the bleeds (Don't know if that affects any anti icing required... no FCOM handy)

I can't quite recall but in my early years on the 737-800, it seemed like we did something similar to that, but I could be mistaken.

Thanks guys.
