Prospero Thanks for including AS in your beta and good luck with your project. The diagrams look great. FTers love detail.

My suggestion is to add a designation (e.g., a blue square, like the green arrows) for Premium Class (and AA's MCE) seats to your diagrams. And the Airbus A321 when you are able.

To highlight your very useful thread for the AS faithful, I made your thread a sticky for the time being.
