Avoid Airplane Seats that Stink

Economy class seating on airplanes is bad enough; the last thing you want is to be shuttled into a particularly terrible seat that doesn't recline, has no tray table, or just plain stinks. Here's how one disgruntled customer described his seat next to the lavatory on one plane [PDF, complete with illustrations.]:

It's difficult to say what the worst part about sitting in 29E really is. Is it the stench of the sanitation fluid that's blown all over my body every 60 seconds when the door opens? Is it the wooosh of the constant flushing? Or is it the passengers asses that seem to fit into my personal space like a pornographic jig-saw puzzle?

How to avoid such a fate? Use SeatGuru.com, a website that breaks down every airline by its planes, and then presents you with a diagram of the interior of the aircraft that tells you which seats have which amenities and drawbacks. Then, when you buy a ticket, you can pick out the seat that fits you best. The site also lets you prepare for your flight beforehand by letting you know which planes have meals and power outlets. (In some planes, only certain seats can access the juice.) Now, if only there were some way to figure out how to avoid sitting next to the screaming baby.
