It is not a direct quote, so it could just as well be an interpretation by ST based on the fact that Flybe is konwn for its large Q400 fleet.
Generally speaking, the Embraer 195 will need to find new work at some point. Most of the new services from CWL, DSA etc. will hardly continue once the "partnership" with the airports comes to an end and the E95s would need to earn money on a purely commercial basis. They would be a good fit for domestic services from LHR.
