One of the two DSA based E195s changed to a E175....so I guess in theory both could go to the smaller jet. Likewise at CWL and NQY maybe those routes could change to the E175 with a slightly increased schedule to accommodate the drop in seat capacity.
If the Dash has been used numerous times on the SOU sun routes I guess that could become a more permanent solution rather than losing sun routes altogether from the Flybe network. What were the loads like on them? The dash doesn't bother me but did many people get turned off by it and not use the Flybe service?
