For a multitude of reasons, I am glad I cancelled my UA booking to OGG and went with AA mid-March through DFW on their 777.

My best guess is at least a week or two total grounding, with some aircraft gradually returning to service thereafter as their inspections are completed. The fact that P&W has to do the inspections at their shop in Connecticut makes the process more time-consuming. Full return to service could take a month or more.
...perators must conduct a thermal acoustic image (TAI) inspection of the large titanium fan blades located at the front of each engine. TAI technology can detect cracks on the interior surfaces of the hollow fan blades, or in areas that cannot be seen during a visual inspection.

Is P&W the only place that these inspections can be done? The AD says this:
I've been in UA hangers where they were performing similar tests on 737 fan blades (during a 2018 737-NG grounding IIRC) and I know that fan blade inspections can generally be done in MX hangars.

Under the AD, P&W will perform the tests at its facility in Connecticut, and released a statement saying that it is requesting all affected parts be sent to their facility to comply with the AD. The issue is that only P&W technicians have the training to identify the potential failures using the TAI technology... although that training (specifically the insufficiency thereof) was also the subject of March 2019 AD in the wake of the last UA PW4000 failure SFO-HNL in 2018. If it can be demonstrated that other repair stations have the capability and training to performt this inspection, it's possible that the AD may be revised, but for now everything is going to Connecticut.
Have to assume the P&W 777 flight I'm supposed to be on in under three weeks will not actually be operated by that aircraft type.

My flight to IAD next Thursday is still showing a 777-200, but zero’ s out in F. My Magic 8 Ball said “Ask again later” to my question of “Upgauge or downgauge?”

The FAA considers this AD to be an interim action. The FAA anticipates that further AD action will follow
Currently have an ORD-MCO flight for late next week supposedly being operated by a 777-200. We are in first, and don't really care if we get swapped to a non-lie flat seat if they change to a single aisle bird. What we do care about is being downgraded into a completely packed coach cabin. At this point do you think UA would allow us to change to the earlier flight with NO fare difference? I have no UA status and never seem to have much luck with the non-US bases agents at UA....so hate calling them unless i absolutely have to.
Your Magic 8 Ball is pretty accurate.

I looked at the seat maps tonight and looks like there are 210 seats full in economy. Plus unknown number in first.
I can see this playing out many ways:
Switch to a 787-8, which would be great.
Switch to a 767-3, which would be ok.
Switch to a 757-3, which would stink in seating configuration but be cool because it’s a rarer bird.
Switch to a 757-2, which would be kind of ok.
Switch to a 737-9, which would suck in every way imaginable.
Any of you experts see any of these as impossible or more likely?

For a 2 hour flight - that bad? My LAS-SFO flight last Monday was a 737-900, I thought it was perfectly fine - I enjoyed the DirecTV

UA has now zeroed inventory on my March 6 flight SFO-OGG, which is supposed to be on a Polarized 772, and has basically pulled the 772 flight (1273) off the market in subsequent weeks as well.
Given the slack in UA's long-haul fleet, I will be unbelievably pissed if they cancel or downgrade us.

You may just be the nly person who likes the UA 4-across section on the HD configured 777.

Novice here. What is the best way to try to see what type of plane is assigned for a given trip knowing that it is always subject to change up until departure? I have a flight from EWR-SFO that is coming up over the weekend that was scheduled for a 772. From what I can tell the seat map was always showing 18 rows in J so a swap to a 77W was always possible. Not sure if that is what they are most likely to use given the circumstances or if the 777-200ER are also being used on the route. I know it is all a toss up but just curious. Booked row 9 which I assume is pretty much the same in either variant.

Is there any chance at all that UA decides to permanently retire all the PW-powered 772s, even though quite a few of them underwent Polaris retrofits not too long ago?

There is certainly a chance, but I'd doubt it. Most airlines like UA buy "power by the hour" so I'd bet that P&W or some bank that owns the engines is likely picking up the tab for at least some of the costs ...ciated with the grounding.
