The ATL base is all rumor so I would not put in an app based on the hope for one. Even if they do start one and you get hired, who is to say you will be on the crj900? It is not your choice. The company gives you the equipment and you pick the base that your seniority can hold. If they start a base in ATL, expect it to go senior so if you haven't been hired yet, you are probably out of luck.
