New year, new cancellations:

1/1 UA835 ORD-PVG 744 Cancelled due to aircraft maintenance
1/1 UA946 IAD-AMS 763 Cancelled due to aircraft maintenance

therefore:
1/2 UA836 PVG-ORD 744 Cancelled due to aircraft maintenance
1/2 UA947 AMS-IAD 763 Cancelled due to aircraft maintenance

also because UA863 on 12/31 SFO-SYD diverted to HNL:
1/2 UA840 SYD-LAX 772 Cancelled due to aircraft maintenance


interesting fact: according to the first post in the 2015 thread UA946 cancelled on 1/1/15 (due to maintenance) as well. maybe you'd want to avoid that flight in 2017.

looks like we're in for a long thread again this year.
