I know someone how works for kosmar and they will be adding these routes for 2006 may not be newcastle but kosmar really does support newcastle as a point to fly.
Libra never did turkey until this summer.
Excel winter base
They are hoping to base aircraft at newcastle for the winter season but upto now they need some work.
Maybe Mytravel will pull out in winter and let excel pick up the work??
Kosmar will be adding flights in winter also.
