Edited to add that in googling, "what is the BA YQ charge for", the words "fuel" and "charge" come up pretty much every time from multiple sources.
So what is YQ exactly for then nux?

It is still (incorrectly) referenced as a fuel surcharge.
It is also often referenced (even more incorrectly) as a tax, just do a search on FT/Google for "YQ Tax".
