Flying to London, and on towards New York is literally a dream on board Virgin Atlantic’s Boeing 787-9 Dreamliner. (From London-New York it’s on the A340-600.) With daily flights to Heathrow from New Delhi, the smoothest way to do this is inside the airline’s Upper Class, in a luxury leather armchair that literally cocoons you in privacy (thanks to the clever angle of the seating), and turns into a fully flat bed with a comfy mattress (for which it’s won design awards). You’ll also get a pair of pyjamas and slippers.
