Utilisation does appear to be very low, some aircraft doing one return short trip a day.
BA Cityflyer make their E jets work hard, during the summer week-ends once London City winds down, their E jets are working day & night to bucket & spade destinations from the regions. Winter week-ends they're heavily deployed on ski flights also from various regions.
Why aren't the Flybe E jets working into the night from BHX/MAN/SOU on bucket and spade flights? are they really scared of upsetting EZY/RYR/J2 ? Not held Cityflyer back, their flights might not be as cheap as the other LoCos but have proved to be popular.
Something is wrong with their business model for sure.
