I was on the same flight with you yesterday and it, honestly, freaked me out a little. When they came back on and said, "k, wind's back, we're going now!", my first thought was... ummmm, what if the wind disappears again while we're rolling down the runway??
I think I'm going to stick with the stopping in SFO from now on. I don't need to worry about whether or not my plane has enough runway to take off!

The question is whether the amount of fuel on board (when the airplane leaves OGG) is going to be enough to get all the way to ORD with required reserves. In marginal cases, a flight plan will be filed first to a mainland airport, say SFO, and after a few hours of flight, the crew and dispatcher will look at all the factors to decide whether they can continue safely to ORD. If actual fuel burn, winds or enroute weather turn out better than forecast, the flight plan will be refiled direct to ORD. If not, then it's a gas-and-go at SFO.
Several years ago, UA flew ORD-OGG-KOA-ORD as a circle trip partially because of performance limitations on the OGG-ORD leg. UA uses some very sophisticated flight planning software which has made a big difference in the schedule reliability of many routes at the very high end of a given type's range.

I remember reading something that it was too heavy to takeoff safely and all the seats and some other stuff was removed before they tried (successfully) to get it out the next morning.

CO operated OGG-IAH on the 764 for a few years. Would be interesting to see the comparisons in performance of the a/c on the 772 PW vs. the 764.

Hopefully someone will have the actual numbers, but my understanding is the 764 is a more capable aircraft, hence one of the reasons why the 772A has never operated EWR/IAD-HNL.

I could be wrong, but I though CO flew 762s to the islands. My IAH-HNL was on a 762, so kind of doubt they would have put 764 on OGG route.

Still minor %. And Alaska will not fly to Hawaii if it has to use anything other than a 737. UA doesn't have this problem out of LAX/SFO.
I wouldn't be concerned about this, there's a lot of safety oversight and planning for runway performance.
Well arguably the Qatar 777 at Miami only using 8500 ft with an intersection departure and taking out the approach lights. May have been doing a derated takeoff thinking they were going to use the full length rather than an absolute limitation of the aircraft.
Southwest put a 737 into KPLK (3700 ft runway) not too long ago (and got it out).

Back in 1998 a United DC-10 flight 100 from ORD-BWI was diverted to IAD because of weather, then IAD also had issues and they had to divert to DCA....and its 6,800 foot runway.
I remember reading something that it was too heavy to takeoff safely and all the seats and some other stuff was removed before they tried (successfully) to get it out the next morning.

"the three-engine plane, carrying a relatively light fuel load, made it easily into the air around 9:45 p.m., and reached BWI shortly afterward, according to an operations officer at National. Carrying no passengers, but with cargo and baggage still on board, it lifted off about half way down the runway, he said.
...
By 7 p.m. the passengers from United Flight 100 were on buses chartered by the airline and bound for BWI."
So, only a few feet shorter than the runways at their main hub, MDW :-p

CO flew 764s to the Islands; any 762 service would have been an equipment sub. A point of confusion was when CO introduced a high-density configuration with the 764 (20J instead of 35J) and coded it '767' in the various timetables. IAH-OGG was scheduled as a 764 while it lasted. EWR/IAH-HNL were 764s from the retirement of the DC-10s through the merger.

Not a 777, but some (10-15?) years ago a business jet landed on the wrong (short!) Colorado mountain airport and had to be disassembled to depart via truck.

CO used a 764 IAH-OGG. Had the pleasure of riding it many times. Plane was used to open IAH-EZE after deep sixing the Maui route.

Flown them both, 772A eats 764’s lunch. If anything the 764 is a bit of a runway hog on takeoff. 772A could easily fly East Coast to HNL so performance is not the reason it hasn’t been operated.

That 737 was still in service with WN until last year. Always hoped I'd get a chance to fly on it, but never did.

HNL doesn't have runway issues like OGG, so presumably it has more to do with optimal deployment and the number of seats UA can sell on that route, with the 777 being better used on other denser routes.
