Have you ever imagined being able to sleep in a double bed at 36,000 feet above sea level? Neither did I, until I discovered the Singapore Airlines sequels earlier this year. Imagine this: a private room in the sky, not just a seat, but a full-fledged bedroom with a luxurious mattress, soft pillows and a high-thread count duvet, all designed by Givenchy. But that’s not even the best option. Etihad Airways’ “The Residence” goes further by offering a Savoy-trained butler and a private bathroom with hot water shower. Sure, private jets are the ultimate luxury, but for most of us, these commercial options offer a taste of the high life.
