I honestly don't see a problem with the Dash. I found them clean and comfy, not too loud, onboard prices were cheap and the Newcastle based crew friendly and were so helpful and as an airline they provided me with fantastic value for money.
Long live the Dash, even in that nauseating purple paint job. If it wasn't for the Dash, many routes would not be possible so credit where it's due.
I admit I wouldn't want to cross Europe on one but for a quick hop within England I honestly can't see the problem. Legroom wasn't great, but where is it great these days?
