This week Emirates has been showing off the luxury trappings that come with its extravagantly-customised Airbus A380s. The superjet carries 489 passengers in varying degrees of luxury. Shower spas, temperature-controlled floors, 23″ screens with over 1,000 audio and video channels, a bar and 14 first class suites are among the features to look out for. Sounds more like a cruise ship than an aeroplane. Expect a first class ticket New York to Dubai round trip to be around $14,000 (for business class, $9,000).
