Before flybe came along the route was served by a maximum 50 seater and when shared with PLH that would have been an allocation of circa 25 seats 3 or 4 times daily.
Something in the SF340, Do328, ATR42 range is what will serve the route viably, to hell with cheap fares for the leisure travellers, a viable air link is essential for the Cornish and some Devonish and if the leisure travellers don't want to pay the fare then there is always the train, the A303, or if they can't afford to go on holiday then they stay at home
