My guess is that they have also an air taxi certificate (Part 135) that they do sightseeing flights. Doing these flights under Part 121 certificate would be too expensive. They also could not fly Part 121 ops into the airports they do. Both North Vegas and PMD are GA only right now (though PMD has a terminal that LAWA built).
