The greatest airplane beds in the sky

The most luxurious thing in the sky is to stretch out on a fully flat bed and sleep your way through a night flight, arriving refreshed the next morning. These are some of the best in-flight lie-flat experiences available for when we can all fly again.

(CNN) — The most luxurious thing in the sky is to stretch out on a fully flat bed and sleep your way through a night flight, arriving refreshed the next morning. It can certainly be pricey, though, with many business class seats running into the thousands of dollars, and first class sometimes into the tens of thousands. But whether you've managed to fork over the fare (or the frequent flier miles) for the very best of first class before it disappears from our skies, or are flying the increasingly attainable yet increasingly luxurious business class, these are some of the best beds in both classes for you to consider.
