It's dining, elevated. We're talking about airlines that replace limp chicken with, for instance, a confit of king prawns with marinated-asparagus salad, and flights where onboard chefs prepare a parade of courses while an in-flight sommelier finds the perfect wine to accompany each new dish. It's time to trade that plastic meal tray and rickety tray table for fine bone china on delicate linen. Get ready to feast your eyes on the most elaborate meals in the sky.
