QWERTY,
Dart has threee different business models in the aviation group.
The monthly "milk cheque" from the Royal Mail contract that underpins the winter ops and negates the losses .
The charter section that has beaten its budgeted target by March this year and has grown rapidly as others in the UK market have gone to the wall.
And finally the bread and butter Lo Co operation, that has seen a significant improvement in yeild management where sometimes less is more.
All contribute to the bottom line, some more than others, but importantly it doesn't rely on one method.
