On a previous contract renewal, Citywing (in its former guise) kept services on sale whilst contracts were being sorted out. I can only assume that it not doing so on this occasion is a sign that contracts aren't being sorted out and it's therefore going to another operator. May be wrong, but I can't see this as a good sign.

"We have heard of two operators that have applied for the route so should be pretty safe."
