Some time ago I found the site SeatGuru.com. It helps you plan your trip by giving you the layout of each aircraft from numerous airlines. They help you know the difference between superior and substandard seats which is great when booking online. I’ve used this a few times while booking my flights, you should check it out!
(If you want to read about reviews with different airlines check out the topic Airline Review.)
Using SeatGuru and checking online exactly 24 hours in advance could score you the ultimate seat at the regular price! I always set my alarm 24 hours in advance (even if it’s 4am…) to make sure I can change my seat if needed and this has definitely made my flights more pleasurable.
From the About SeatGuru page:
The SeatGuru staff flies over 250,000 miles each year, but we still can’t fly on every single plane, which is why our visitors are so important. Through a “Submit Comments” link on each aircraft web page, thousands of reviews have been submitted to the SeatGuru database by other flyers who enjoy a great seat. The SeatGuru staff utilizes these comments to maintain the accuracy of our airplane seat information and updates the site weekly with both user submitted reviews and independent research.
In addition to the incredible response from all our contributing gurus, we also receive a great deal of information from pilots, flight attendants, and airline personnel who’ve taken the time to write in and share insider tidbits with us. Thank you – we smile every time we sit in a “green” seat.
