Pros: Plane was spotlessly clean, smelled nice, bathrooms also very clean and had toothbrushes and toothpaste. I requested the vegetarian meal and it was the best airline food I have ever eaten Flight crew was friendly and seemed to genuinely enjoy working for Japan Airlines. I don't see that very often on any domestic US air carriers. I highly recommend Japan Air.
Cons: Headset was too big for me and kept skipping back.
