The people doing the Charlotte
PR are saying the expected marketing script and prose
But most marketing I have seen usually centres around 'route doing well', 'happy to be serving the route' or 'supports X number of jobs' etc.
Specific details about future scenarios, such as extending to year round, or adding more flights etc normally comes into play when some behind the scenes scenarios have been discussed in depth.
For example, Saudia stated 'we are looking at adding more flights to Manchester by the end of the year'. Hey presto, a 4th flight is already appearing in some GDS systems.
Therefore, 'look at potential go year round' announced to the public, to me translates to 'we have done some sums, had some meetings and its actually quite a serious proposition should the route perform how we expect'.
