That's because of Chautauqua's recent announcement that it will not be able to renew the American Connection 44-seater contract because of its pilot staffing troubles and those 15 planes will be parked between now and August 15. Apparently Skywest has adequate pilots to staff some CRJ200s on a short-term basis. Within a couple of years, AA's Chicago regional operations will consist of almost entirely E175s and CRJ700s (two-class RJs). The 50 seaters and 44 seaters will disappear faster than earlier planned.
