Emirates

The service on Dubai-based Emirates, an 18-year-old airline, has taken first-class pampering to new heights. Emirates recently spent $1.8 billion installing upgraded amenities across the fleet, including "first-class suites" on its A340-500 planes. The suites consist of leather convertible flat-bed seats with massage functionality, down pillows and cotton-lined blankets. Seven-course meals are served on Royal Doulton bone china with linen napkins.
