Perhaps 30 minute turns won't happen but having an hour on the ground is plenty for our operation.

Whether it takes 90 or 10 minutes for a PDSC is immaterial. What the FAA says it will take is what counts. No official table-tops have occurred.
APU will be running from engines start to EXP. OPS SPEC for APU reliability is expensive and might come later.
We strictly are following what the two principle ACs say in the matter of ETOPS certification. We are neither under nor over doing it.
We have rather difficult Feds to deal with. Not to mention we are at the end of the year and scheduling Fed time is difficult.
Tech Ops has the most difficult job.

From: 747 Captain (Ret,)
The biggest cost of the continuously running APU is for flights that routinely depart at max structural gross weight. Then you have to reduce payload (pax) by the weight of the APU fuel burn planned. Call it 1? 2? pax kicked off for each hour of planned APU operation. Depending on ticket prices, this can add up fast.

Planned burn for ETOPS is about 350 lbs. total. (Straight from the flight plan)
One turn back and burn off to get below MLW would very cost prohibitive.
Planned icing encounter, which must be accounted for in planning, can be more than fuel burn.
The APU Ops Spec, is very expensive because the aircraft that are to be designated have to be continuously monitored and managed. That is, they have to be routinely started inflight while domestic. Record-keeping for and the management of ETOPS aircraft is the difficult part, by far. One mistake can be extremely costly even if no one is hurt or aircraft is damaged.
MAX performance much better than the NG and there only 28 or so to be used.

We have APU on demand at UAL and we operate over 350 737s. Really not all that hard to track. From time to time, we get a message asking for a reliability start enroute on a domestic leg. We cold start it when conditions are met and send a code and it gets logged appropriately. Easily accomplished. We send the MAX-9 to HNL occasionally but I've never flown anything to the islands but the NG (and of course the 757-300 and 767-400 years ago)

Sorry? No is saying you not pursuing it. We are just wondering when you are ever going to get it.
News flash, you were suppose to be selling tickets by now.
I for one can't wait to hear cowboys on HF.. :"YeeHaw, This is Souwest737, we runn'in a little late, request block 320-360 direct HNL"
