Mr. Maloway, having recently finished my studies in the field of aviation, I know and I would like to inform you that airlines are not even able to determine the profit they make on a given route. Consequently, it would be rather difficult to determine the impact of that figure. The network is extremely complex.
Since we are not able to generate or to identify the profit that is being made on a given route, I am not at all surprised that they are having difficulty answering your question.
