Having plants around the place seems to freshen the air and provide a more relaxed atmosphere. These would both be particularly useful effects in an airliner.

Today’s invention is to provide passenger jets with beds of low-mass hydroponics substrate and to fill these with living bushes. The moisture in the exhaled air of the passengers, and from the galley, would be condensed and fed back to the substrate.

In the event of an emergency, the bushes could also provide some added protection from the airborne contents of overhead lockers.
