Continuing Saga of My Return to Japan: Flight Canceled Again

For those hanging on the edge of their seat as to my travel schedule, here's a short
followup to
“Got to the Airport a Day Early to Find my Flight Delayed Four Days”
and
“Finally Got My Return Flight Rescheduled”....

TL;DR version: Canceled again.

I was supposed to leave Akron Ohio this evening, but United Airlines
canceled my flight (again), and not due to weather (again). Both times now
it's been canceled well in advance of the actual flight. My educated guess
is that they decide they need the plane more importantly elsewhere.

Anyway, the current schedule now is to go out on Sunday night, stay in
San Francisco on Sunday night, leave from San Francisco on Monday morning,
and arrive in Osaka on Tuesday night.

We'll see.

Update: big thanks to the hotel I'd booked for my overnight in
San Francisco, The Dylan at SFO, for
allowing me to move my reservation to the new day even though it was past
their cancellation-cutoff time.

Update: on a whim I took a look at the how the Chicago→SFO flight I was supposed to be on is doing,
and see: “Estimated Departure 1 Hour 38 Minutes Late (Delayed - Cargo loading)”. Ugh, glad I missed it, I guess.

Update: now it's “2 Hours 13 Minutes Late (Delayed - Aircraft
servicing)”. I guess I shouldn't be
surprised... looking at that flight's
history on FlightAware.com, it seems to rarely be less than an hour
late getting out, often much more. It looks to have gotten away on time only
two or three times in the last month. Ugh.

"Statistically, when taking into consideration sample size, standard
deviation, and mean, this flight is on-time more often than 0% of other
flights." — flightstats.com giving it the worst
possible score in on-time performance.

Watching the connecting flight I'm supposed to take on Sunday get more
and more delayed (now almost three hours), and considering that it has
almost a 0% on-time rating, I just changed my reservation to a direct
flight out of Cleveland. It's less convenient, but less chance of stranding
me.

Half an hour ago it said "Departed Gate 2 Hours 35 Minutes Late, taxiing to runway (Delayed - Aircraft servicing)", but it still hasn't taken off. Glad I switched.

Final? update: it took 45 minutes after it took off (and after FlightAware.com started showing realtime data) for United to update the status to “in flight”.
