What are the classes of airline seats of different airline carriers?How or where can i get them?

Anybody out there who could help me on my research on the classes of airline seats of different airline carriers?classes of airline seats and it's classifications like business class, economy class, etc.

Go to the airline's website. When making a reservation, look at the different classes of service.

Go to http://www.seatguru.com

That site lists all the seating configurations by aircraft on just about every major and regional airline flying. Gives width and pitch information too.

If you are talking about "classes" of seats not just by coach/economy, business, first ect and are interested in Y,K,Q,M ect, those are fare catagories, not seat catagories. For example in coach you may have all of those fares and as the plane sells out only the Y fare will be available as that is the code for a full fare, unrestricected coach seat (walk up price).
