(for reference, N20904, the 787-8 originally scheduled to do IAD-CDG and subsequently my flight today, has had flights rostered but later removed, and hasn't operated since Dec 20; it may have gone tech aka out of operating service)

Today’s second aerial carriage is @United’s Boeing 787-8 N20904 on UA182 DEN-FRA Believe it or not, that’s my first 787 flight. #avgeek

on my way back to the hotel last night I was curious which frame would operate the flight

the inbound SFO-CDG arrives too late to turn back to SFO at 9 AM, so I looked at other United hubs; ORD/EWR didn't fit whether in sched or plane, and the answer was IAD

...of course it swapped and got delayed
Flightradar24 app screenshot of a United Airlines flight from Washington to Paris that arrives at 6:55 am; early enough to fly the user's flight to SFO at 9:00 am. The listed airframe is a Boeing 787-8 registered N20904. The same flight after being delayed nearly six hours and swapping to a different Boeing 787-8, registered N26906.
