The -300ER with the Cf-6 engines and 777 displays is an awesome machine. Think 767-400 with better performance and range.
They need to do something about the current -300 fleet. They are pretty tired and Honeywell is no longer making CRT dislplays, so the panels in the current fleet will need upgrading pretty soon. Rumor is that DAL has bought all spares available on the market.
Excuse me if I don't see the scope bogeyman under every rock.
