European discount airline RyanAir is proposing a special kind of budget "seating" for some of their planes:
Instead of being allocated a seat, Ryanair travellers would perch on a narrow shelf and lean against a flat padded backboard.
They would be restrained with a strap stretching over their shoulder, the budget airline said.
Click through to the story to see an artist's rendering of the proposed seats. Basically it looks like the seating on modern roller coasters. To be honest I wouldn't have a problem with this for short flights.
