I agree with you, to the extent that I frown every time I see a large aircraft being operated by a regional airline.
Did your pilot group, or did you pilot group not vote to allow this to happen? I have no idea what company that you work for but I would assume that in some way or another you voted to allow this. Odds are that the details about large RJs were glossed over in favor of more interesting things such as your pay going up again. Not a personal attack at all. Your comment just allowed me to make a point. Thanks for understanding that regionals are not stepping stones.
