So a bit of a digression for which I apologise, however since it’s been mentioned:
BA aircraft never take part in LAHSO. Which is why it is promulgated to every ATC unit.
In the US, the danger is not so much that any BA aircraft would themselves be instructed to LAHSO. Far more likely is that a smaller aircraft would be instructed to LAHSO on a shorter intersecting runway, allowing BA to then roll through that intersection on the longer runway. For BA that’s not acceptable.
The US is almost always a very challenging place to operate as far as their ATC is concerned. SOIA being another challenge, and of curse there’s the language barrier!
The US is clearly happy with their procedures, BA is less so and have declined to take part in LAHSO.
I know other regular contributors here are intimately familiar, and will correct where I’ve been getting it wrong all these years!
