When it comes to airplane cabins, many airlines and manufacturers have been rolling out designs that seem to perpetually squeeze passengers into oblivion.

But not all aircraft designers want flyers to feel like a canned sardine.

At the Crystal Cabin Awards, an annual showcase of airplane interior designs presented by the Hamburg Aviation Cluster at the Aircraft Interiors Expo, inventors present a range of seat designs, airplane interior makeovers and technologies that have the potential to make flying much, much better in the future. Categories range from passenger comfort to technologies that promote greener or more environmentally friendly energy use to interior cabin design concepts.

The final awards are presented April 5 but the top 24 finalists for 2016 were just released by the award association. Here are a few of our favorite designs we'd like to see on aircrafts of the future.
