With regard to Air Anglia and the F28, Peter Villa at that time Chief Exec of Air UK is quoted in an article on Air Anglia in 'The Aeroplane' January 2017:
"They put 85 seater aeroplanes on what had previously been operated by 44 seat F27s, and they put F27s on routes that had been operated by Chieftains. The traffic didn't come up to the requirements. I don't think they'd really worked out the market potential - it very rapidly became obvious they were loosing a fortune".
