With apologies for starting another thread, but this information seems to be all over the place right now, so hoping perhaps to consolidate (and avoid some of the off-thread conversation that's occuring on threads that have grown so long).

I'm flying GRU-LHR in J in two days. I'm imagining there'll be no food and no beverage, with perhaps vouchers passed out at check-in.

Will there be wash bags? Anything besides tank water on board?

Sounds as if some crews will allow self-bought alcohol on board. Some may allow heating of meals.

But, otherwise, no service, correct?
