Fuel prices are rising once again. So, prepare to get to know the guy who smells like Axe body-spray in 3A a whole lot better. Airlines are shrinking legroom on planes across the board.

Everyone from American, to JetBlue, Southwest, and United are looking for creative ways to save money and increase revenue beyond fare increases, and charging add-on fees. Many airlines are adding seats and decreasing legroom in the economy section by reducing seat pitch - the amount space from one point on the seat to the same point on the row ahead - swapping out thicker seat cushions for thinner ones or installing new seat architecture.

I don't need to tell you how important legroom is --whether you're six-foot-five or have the build of a thirteen-year-old girl (me), you need your space. Legroom from one aircraft to another even on the same airline can differ.

Which airlines are making changes that are not-so-friendly to your knees? Read on.

Southwest Airlines:

Southwest began retrofitting its fleet with a new interior in March. Seats are now six pounds lighter than previous models with thinner cushions. In a blog post on Southwest's website, the airline admits this allows them to increase the number of seats on board from 137 to 143 on some aircraft. It claims that seat comfort and space isn't sacrificed, but hey, you do that math and see if that means less space.

JetBlue:

JetBlue announced this month that the company has added enhanced legroom seats, dubbed Even More Space, to its fleet of Embraer 190 aircraft. Of course, this has come at the expense of a tighter seat pitch for those seated further back in the coach cabin.

United Airlines:

United went with popular European manufacturer Recaro when selecting new seats for the cabin overhaul of its Airbus fleet. Slated to begin next year, United's 152 narrow-body Airbus aircraft will be fitted with slimmer seats. The airline also claims seat comfort won't be sacrificed, but the refit will enable an extra row of seats to be added to each aircraft. So, yeah ... Really?!

American Airlines:

American's new Boeing 737-800 aircraft has two additional rows of seats over its other 737-800 configuration. Seat pitch has been reduced, but to mitigate the 1-inch less of space, the seats do not recline. Instead, the seat bottom slides forward while the back slouches within a shell.

What does it all mean? Unless you're a frequent flyer, a club-member, or somehow afford flying first or business class, planes are about to feel even more like cattle-cars.
