SeatGuru - essential

Use SeatGuru to search airplane layout charts before you select your flight seat so you'll never again be stuck with only partial reclining ability or in the back near the stale coffee. SeatGuru calls itself "the ultimate source for airplane seating, in-flight amenities and airline information" and it works -- I've used it. Even though the site is intuitive, there are directions right on the home page.

It's simple: Look up your airline. There's all kinds of info that you can navigate using the tabs that pop up, such as baggage rules, traveling with infants, policies regarding unaccompanied minors and travel with pets. Amenity info is listed, along with phone numbers that may be of use, all specific to your airline.

To get to the good part, the seating chart, break it down further by type of plane. A cool, color-coded chart assists you in picking the best seats for your needs (long legs, near the bathroom, not near the bathroom, etc.). First-class is included. Here's an example.
var gaJsHost = (("https:" == document.location.protocol) ? "https://ssl." : "http://www.");
document.write(unescape("%3Cscript src='" + gaJsHost + "google-analytics.com/ga.js' type='text/javascript'%3E%3C/script%3E"));

var pageTracker = _gat._getTracker("UA-3425016-1");
pageTracker._initData();
pageTracker._trackPageview();
