Next month I am flying on the NW18 from HKG to JFK. I have bought the cheapest tickets going at about $270. Where is the best place for me to try and get seated?

I have never flown NW before so am not quite sure what to expect. I have no status with them or KLM. I do have Emerald OW status if that hepls? Probably not.

Many Thanks in advance
