On most flights within or between the United States (including Alaska but not Hawaii), Canada, Mexico and the Caribbean – what is normally regarded as regional business class or premium economy in the rest of the world is branded as "domestic first class" by US airlines. The service is generally a step below long haul international business class.[4] US territories in the Western Pacific (Guam and the CNMI) and sometimes Hawaii are considered international for service purposes and generally feature long haul business class.
