If they are reporting 50% to 60% loads for the whole set of new routes, then I would be inclined to think LGW/Casablanca flights are going to be at least three quarters full to make up for the shortfall here
as for CX, I too have seen their City Centre advertising last week and also ads in the Evening News. I wonder if they will maintain these level of advertising for the next 6 months but must applaud them in spreading the news of their services as widely and as early as they have.
