You could maybe add seasonal loads like for example in the winter, places like DEN, and SLC will have more loads for winter sports and MCO, FLL, MIA, HNL, OGG, and KOA see increased loads for winter vacation. Another idea is the possibility of advertising. You could advertise your airline on the TV, radio, newspapers, billboards, or leaflets. You can also advertise your airline for an increase of loads for a certain route to help create larger loads on a smaller flight or have a big campaign to just have an overall increase of loads for all flights.
