All Nippon Airways

ANA's first-class cabins feature wide, 33-inch seats that convert to beds--silk sheets, down duvets and sleep suits all provided. Each seat has its own 15-inch monitor with on-demand audio and video entertainment, and ANA's EUPHONY sound system filters out background noise like engine hum or passenger chatter. Krug Grand Cuvée is served onboard with Iranian caviar as a welcome treat, and hot, freshly cooked rice is served with every meal.
