So I'm planning an IAD-FRA trip for the first week of November. Looking at the schedule for 952 and 953 for the next 7 days on unitedcargo.com it seems like every day 952 and 953 are operating as a new config (67I).
Is this possibly true? Is there a pair of new planes running this route? If so, 952/953 might have just become the best flights in the whole system for me.
On a slightly related note, I notice that 916/917, the 747 flights (which are currently a mix of old/new) change over to a 777 in late October. The last flight on a 747 for 916 is October 24, and the last 747 for 917 is October 25. I wonder if that new-config plane is going?
