Thanks for the responses.

I wish I could afford the ANA premium economy but it is very expensive. Maybe someday.

United or Delta....... I guess they are prob about the same so I will prob choose United due to having some Star Alliance miles already. But the extra recline sounds pretty nice.

Edit: I am not a big flyer (if you can't tell haha) So would it be dumb to choose Delta this time and accrue miles with them vs United. I have about 12,600 on Star Alliance/United Mileage Plus. I assume it would just be better to keep adding to those miles, esp on a long trip like this?
