Been flying out of AZO for years - 220 segments last year, 120 on CRJ1/2's. I booked a flight from AZO to MLI on 2/18 and to my surprise, a CRJ900 showed for the 5:45am AZO DTW flight! And, my return on 2/20 is also a CRJ900. So, I looked at the DL flight schedule and it lists CRJ900 service is only from 2/17 until 2/28 then reverts back to a CRJ200. Say it isn't so! Is this a test? Will DL eventually make this route a CRJ900 route for the peak flights?
