Guests in Etihad Airways “The Residence” aren’t just treated to a comparatively-large amount of aircraft space, they’re also provided their own private butler. This isn’t just a glorified flight attendant either, it’s a butler trained at The Savoy in London. So while you’re kicking back with a book, watching a movie or joining the mile high club in your own private bedroom, you can always buzz the butler for a refill on whatever it is you’re sipping. In terms of brand-name commercial jet air travel, it doesn’t get more luxurious than this. For $20,000, however, you might consider chartering your own flight. If you have this kind of money, we imagine the decision isn’t much of a problem.
