Only two US-based airlines fly the Airbus A220-300 and A220-100 out of the United States on five routes. These are JetBlue and Delta Air Lines operating A220-100 and A220-300s. While Delta Air Lines is one of the oldest, largest, and most highly rated airlines in the United States, JetBlue is a large low-cost airline founded in 1998 that operates a hybrid business model. According to information from Cirium, an aviation analytics company, these five international A220 routes are leisure routes taking holidaymakers to sun-soaked tropical island destinations.
