In a real world yes but who knows in this COVID world. As previously mentioned Eastern just seem like a good fit for most of the ex Flybe routes ex CWL especially as they already have the based J41 and serve both VLY & BHD.
It would be great to see them base an ATR or the E70 here especially as no competition but it is all going to be on recovery from this pandemic in the long term and what deal/incentive CWL would offer any airline to pick up these key routes (DUB, EDI, JER, CDG).
