First time flying with the new 777 and this is the current availability:



It's a 3 am flight overnight and I'm at 11K (window) right now with a stranger on the aisle seat next to me.
However the middle 3 are completely free (flight is in 12 hours) and there is also the 8K & J that are empty (which are bassinets: is there a downside to bassinets seats, if nobody books beside?)

Suggestions? And would the window seat in the new 777 easily be able to go over the aisle seat for toilet needs?

Thanks
