This has completely confused UA's systems. For example, the App thinks the aircraft which will operate UA837 SFO-NRT this morning is still at ORD.

Further, there appears to have been a diversion on one of these flights to ORD, which is apparently why Flightaware shows the first departing from Fond du Lac rather than FRA.

I agree, I've always seen/heard a 2xxx for the make-up.

Then there's the situation I saw yesterday, tracking our incoming aircraft. We were on UA 1728 OGG-SFO, so I was tracking incoming UA1725, and FlightRadar24 showed two flights, one following the other, both the same aircraft all the way from SFO to OGG! No IRROPS, so bug or system interface issue? Looking at the history today, it's normal.
