The RJ issue was never about 70 seat jets. It was about moving the line forward to replace all DC-9 and B-737/500 flying by outsourcing it to lower cost operators thus allowing them to focus on international revenue and transcontinental marketshare. The 90 seat issue will one day give way to the 105 seat issue. Look for the line in the sand to move about every 7 years to allow mangement to focus on premium RASM's. Once you give in, it's just a moving date of destruction for the piloting profession.
