Beggers can't be choosers though.
I know I'd much rather a 5-7 weekly ATR service as opposed to a 4 weekly A320 service.
Also were would the A320 come from? There is no base there, and W rotation planning for just four weekly rotations would be a pain!
I could see Knock getting services on the days Shannon does via a W rotation.
However, I think the actual airline that will step in is Flybe... I'd prefer them tbh too!
