The Emirates Airbus A380 is special. First class features suites with doors, though there are better first class suites. Emirates has an amazing food and beverage program, often including $500 wines and even more expensive cognacs. And it has two on board showers. There’s also the business class bar.
But it’s an expensive product, both spending cash and spending miles. You’ll have to spend a lot more miles than most programs require for comparable travel. Except there’s a route where they give the seats away for less than the wine you can drink on board.
