Sardine Can Airlines: What are the Implications for Travelers with Disabilities? For Real-Sized People?

Spirit Airlines is on a roll. Recently they announced a new carry-on fee, and along the lines of another innovation that may not "sit well" with passengers, the airlines is switching over some of its aircraft to seats that do not adjust. Instead, the seats will remain stationery in a 3-inch, pre-reclined position.

The airline said the slim new leather seats are 30 percent lighter, which means they will use less fuel costs. The space under the seat is also 20 percent larger, which is a good thing since this is, for now, the only free baggage option on Spirit Airlines.

By eliminating a steeper recline, the airline said it can also fit more seats into the plane - 33 more passengers to be exact - in the airline's new Airbus A320 than in an older Airbus model with conventional reclining seats.
