For the larger airlines, the issues mainly centre around the question of brand integrity. If someone books with a major airline, they expect the service to be provided by that airline, using a jet aircraft. With franchising, they may arrive at the airport to find that they are actually flying with the regional partner, and perhaps in a turbo-prop aircraft. However wrong it may be, turbo-props are still regarded by some people as being slow and oldfashioned, and they may feel that the brand promise has not been kept if they have to travel in one.
