I've got a few questions dealing with aircraft quantity. How many 767-400's do Delta and Continental currently operate? How many 764's are they planning on acquiring? Same questions for CO 762er's. Also, how many A330-323X's is US Airways currently operating and how many more are they getting. And the last 2 questions: how many A321's does US Airways currently operate and how many are on the way? Anybody know which routes the A321's are flying? Thanks for your help!
