It all comes down to the operation requirement. A 3 class 777 is configured 48J/24W/203Y and when a 77W operates a 3 class route BA sell the F seats as J and operate the aircraft in a 70J/44W/183Y. The 77W allows BA to add addition capacity in J and WTP without significantly reducing capacity in WT.
BA have carried a number of groups to YUL recently I am guessing these groups have been booked in J and WTP as the flight operated by the 77W have all been full in J and WTP and at about 90% capacity in WT.

Quoting Viscount724 (Reply 4): Flightaware arcraft type data is often wrong. Flightradar24.com shows that 6 of the last 9 BA95/94 flights LHR-YUL-LHR were operated by the 77W. It also shows the aircraft registration
That's interesting. Wish they'd send the 77W here more often.
I'd rather die peacefully in my sleep, like my grandfather, not terrified and screaming, like his passengers
