One customer of mine flew the other week with Flybe from DUS to MAN and back with Tuifly 737-700 to CGN.
He preferred the Tuifly flight to Flybe´s service, because he said that the seats were totally worn out on the 145.
For myself quite like the 145. Even when I fly with my wife on the route, we both like to sit on the A-seats, where everyone has a window.
