Airline companies are increasingly searching for novel tactics to succeed and keep afloat in this competitive industry. By code sharing and forming Frequent Flyer Club partnerships, they can realise new prospects that they couldn't while operating on their own. The potential gains of such initiatives are grand. As overhead is reduced and less popular air routes are shared by airline operators, both the risk and the operating costs are reduced. The increased agility of airline operations means that more business is gained by an ability to share services with partners in response to unexpected low demand.

Question: There are certain services that airlines should offer on their own, without forming a partnership.
Options:
A. true, B. false, C. uncertain
