As I see it NCL would not be providing an approach service, only a LARS service as available and appropriate according to the menu of LARS service - Basic, Traffic, Deconfliction etc. The principal of LARS is that it is a free service to the user aircraft and it is subject to capacity availability. I suppose if NCL wanted to play hardball they could. In any case it surely would be at the discretion of the airline as to whether to use it, not a requirement on the airport.
