UA 176 ORD to IAD is a 3 cabin 767.
It was listed as such when I booked the flight 2 weeks ago. I haven't checked whether this is standard equipment for the route.
I was UDU'd as 1P to C somewhere between the 24 and 48 hour mark. The flight was nc7 when I checked on Friday. Gate monitor shows 5 open business seats with 6 on the upgrade list. Though the seat map only showed 2 free seats on check in.
This will be my first time in the new C so I decided to try out the rear-facing seats. I have some flights to BKK and SYD later this year in C, so this is a nice trial run.
Now if only the Bears could have won it would have been a perfect weekend.
