None of the US carriers hold a candle to Emirates Airlines, as far as service and cleanliness goes. The difference is about like riding in a Cadillac vs a model T. I've also heard that Nippon Airlines was really good.
Maybe you should ask Emirates employees... BTW--it's ANA--All Nippon Airlines. I'll stick with the US3, EU3 and a few others. Cathay Pacific and Singapore have good safety cultures but most of the rest of the Asian airlines, not so much. Too many Asian airlines are stuck in the "honor the seniors" mentality where newer people are afraid to speak up when someone older screws up. That was a partial reason for the Asiana crash in San Francisco a few years ago. A Korean Air captain recently tried to drink on the plane and the flight attendant that reported him got into more trouble than he did.
