15-20 years ago BMI Baby operated frequent full 737 flights to Newquay from the north. Is there not a market to re-introduce seasonal flights to places like Newquay / Southend / Exeter for people from Manchester / Leeds/ and all points north? Equally there may be people in the south who would like to retreat to picturesque spots in Scotland- without the long drive.
Whilst maybe not a goldmine- maybe it would at least keep aircraft & crew ticking over? The Covid crisis is not going to be over anytime soon, until they get a system like airport routine testing & proper track and trace, alternative markets might help survivability ?
