I've mentioned Green America before and their Responsible Shopper project. They just released a report on recycling in the airline industry and it isn't a pretty picture. American Eagle, a part of American Airlines is running about the middle of the pack
I really like the Responsible Shopper area--I got to the airline report while researching mobile phone companies.
This is an easy to use site and provides ratings on a lot of products and services and offers suggested alternatives.
