I have a problem with understanding the bolded sentence below, extracted from a marketing book:
Currently, margins are tight and turnover is dependent on inclusive tours and business travel respectively, with other services bringing far smaller contribution. The concept of the experience curve, i.e. an increased market share relative to competitors which leads to the creation of economies of scale, is appropriate in this context. Not only is it a matter of increasing the volume of sales of tourism offerings across branches that improves commercial return, but also the wider experience applied across all activities of the business, which leads to greater profitability.
Would you please paraphrase it? I know the meaning of every single word but the meaning of the whole sentence is vague.
I think tourism offerings = tourism products. But, what does "the wider experience applied across all activities of the business" mean? Is "experience" applicable?
