The winners of this year’s Crystal Cabin Award were presented their trophies last month during a ceremony in Hamburg, Germany, as part of the Aircraft Interiors Expo trade fair. Launched in 2007 by Hamburg Aviation – an association of the city’s aviation-related companies, research institutions, and educational institutions – the award is billed as the world’s most prestigious prize for innovations in the field of aircraft cabins. The winners are selected by a panel of academics, engineers, aviation journalists, and executives from airlines and aircraft manufacturers.

Here’s a look at some of this year’s winners and finalists and the innovations they have brought or could bring to the passenger experience.
