Yep, the ex-Hainan planes. I flew one of these to LHR the other day.

I'd originally selected an exit row seat (row 40, if I recall) but the system shunted me up (for weight distribution?) to 22H – on board the entire forward cabin was full, while rows 40 and back had maybe 15 people at most. Since BA Silver should get exit row selection, I'd definitely select Row 40 than any of the XLs.
