In 2008, Singapore Airlines introduced their Suites Class, the most luxurious class of flying that is commercially available.
The Suites were exclusive to their flagship Airbus A380, and they go beyond flat beds by offering enclosed private cabins with sliding doors that cocoon you in your own little lap of luxury.
The interior was designed by French luxury yacht designer Jean-Jacques Coste and comes along with a plush soft leather armchair hand-stitched by the Italian master craftsmen Poltrona Frau.
Perhaps most well-known of all, Singapore Airlines became the first and only commercial airline with a double bed in the sky.
However, the experience came with a hefty price tag. With round-trip tickets costing up to US$23,000, it was completely unattainable for most people.
