From today's New York Times (except the photo):
The airlines have come up with a new answer to an old question: How many passengers can be squeezed into economy class?
A lot more, it turns out, especially if an idea still in the early stage should catch on: standing-room-only "seats."
Airbus has been quietly pitching the standing-room-only option to Asian carriers, though none have agreed to it yet. Passengers in the standing section would be propped against a padded backboard, held in place with a harness, according to experts who have seen a proposal.
