Ok, I'll check that.
On flightradar I've found the following:
At 12:40UTC
TU202 (A332) FL360 / 426kts ahead of AC835 (A333) FL340 444kts over Wales & Irish Sea
At 15:30UTC
Same order and respectively at FL380 /460kts & FL370 / 440kts south of Greenland
At 17:15UTC just over Newfoundland shore
AC835 FL380 / 384kts a couple of miles ahead and about 35nm to the left of TU202 FL380 387kts.

Something like that. It's hard to keep track of all the acronyms these days... dang MELs.
I gotta say, the other day it was great fun watching all the other aircraft on our away across the ocean. Above and below; fast and slow.

Very true. Unless you work to keep abreast of this "stuff" it gets lost in the weeds quickly. The North Atlantic Data Link mandates is well worth looking at as there are a lot lights in the end of that tunnel so to speak.
