Aisle? Center? Window? If only the chore of selecting an airline seat was this simple. Before selecting a seat for your next flight, visit SeatGuru. The site offers hundreds of plane diagrams and detailed information on which seats you should book and which you should try to avoid based on legroom, proximity to the lavatories, and other factors.

Trying to decide between business and coach? The site gives you information on seat width and pitch in each class.

The site also shows information on the amenities found on the plane. When comparing long-haul flights, it might be worth a bit more to you if you have your own seat-back entertainment unit instead of the overhead projectors/monitors found on some flights.

Using the site isn’t a guarantee that the seat you want will be available but at least if you find yourself in a “red” seat you can prepare yourself for what lies ahead.

Of course there’s always the chance you’ll get the seat of your dreams only to find yourself sitting by someone who just came down with the flu. Unfortunately, there’s now way to predict that.
