I was not able to pull this up in Google Flights for 2 pax. But, it does seem to work for 2 pax on the Virgin Atlantic website for Dec 6th LOS-LHR return Dec 13th LHR-LOS (one example...). $5644 total R/T for 2 pax.
I can confirm it is indeed for Lagos. I have no idea if this is a good deal or not, but it's not very much more than economy for the same days...
