SeatGuru.com
Seat Guru allows you to research and peruse the seating maps for major airlines across the globe. The seats bear labels, such as good seat, be aware, poor seat, power port, and more. The maps are quite detailed and seating is color coded to ensure easy understanding. All the rest of the plane sections are labeled as well, including bathrooms, exit rows, and closet areas. If you mouse over any of the seating areas, a window pops up that describes the good and bad qualities of the seats and whether they have adequate legroom, etc. This is useful for economy through first class, as not all seats are created equal, even in the same class. For example, two seats in the same area may have differences in leg room of temperature. To use SeatGuru.com appropriately to plan your travels, you have to know what airline you're on and the specific plane model.
