Currently the newly refurbished Air China planes are flying directly between Beijing and New York JFK. The Beijing - Frankfurt flight will soon use newer planes. Finally the new aircrafts will fly in the entire China - North America and China - Europe flights operated by Air China.
I once flew in the business class from PEK to JFK. The seat can be expanded to a 170-degree bed. It was a comfortable journey.
