Unfortunately there were always going to be casualty's as it seem Monarch were trying to reinvent the wheel over night. Charter to schedule and two new bases in the space of six months was always going to be a tough ask whilst also trying to turn around massive losses at the same time.
Quite how they thought they could fill three A321's a week to a new ski destination out of a regional airport I will never know.
It would not suprise me if Munich went the same way.
The question is what will replace Grenoble? Monarch seem to have a crush on with Friedrichshafen in Germany - who knows?
Maybe a little more time engaging the good people of Yorkshire than painting stands and doing photo shoots with Chemmy Alcott would serve them well in the furture.
