Sure CRJ's look good, but do any airlines actually make any money using them. I've been told they are ideally suited for routes that are 1.5hrs and over, anything under that and the cost for high cycles mount up.
Hence the disposal of CRJ's by Flybe and the unfortunate closure of DUO.
Having said that it could be a little cheaper than operating A330's between MUS and AUH. Been on it many times, and it is always a joy in such a large ship, but they must be flushing money down the toilet everytime they do so. I say stick with the Airbus 320's and with what you know. With a company fighting for survival introducing a new type is probably not the best course of action.
Plus I want to fly their A320's, not their CRJ's .
