I'm sorry. I made the change quickly at around 11pm my time (when I was a bit tired) because somebody in another thread here [1] noticed that a 767 wouldn't make it from SFO to LHR. I made two typos in this edit (typo-ing "286" to "287" and "388" to "399"), and have just corrected both. If there are any more issues you notice, please let me know (I'm david AT retool, or commenting publicly here works), and I'd be happy to fix them when I wake up again (in around 8 hours' time).

(The former error is indeed because I confused the outbound / inbound flights. I've taken BA286 quite a few times, but I forgot which direction was which. When I was initially fixing the article I thought it was "BA286" but then looked it up and found it was "287". I then fixed the error in the screenshot but forgot to fix the error in the text itself. Apologies the edit introduced annoying little errors — this is entirely on me trying to do fix something quickly.)
