A number of airlines already fly nonstop between Chicago and Los Angeles, but Allegiant will be the only one to fly the route from RFD.While RFD bears Chicago’s name in its official name, the airport in the city of Rockford, Illinois, sits about 85 miles west of Chicago’s downtown Loop neighborhood. The airport added the Chicago name to its title in the early 2000s in an attempt to position itself as an alternate airport to Chicago’s much busier — and much closer — O’Hare International Airport (ORD) and Midway International Airport (MDW). Allegiant is the only airline with service at the Rockford airport, where it offers either seasonal or year-round service to eight other destinations.Related: Allegiant used to love flying used planes; now it’s betting big on new jetsThe other secondary airport getting new Allegiant service is MidAmerica St. Louis Airport (BLV), which is located 25 miles from downtown St. Louis near Belleville, Illinois. The airport opened to commercial flights in the late 1990s amid concerns about overcrowding at St. Louis Lambert International Airport (STL), the metro area’s primary airport. However, a new runway at STL coupled with declining flights — American dropped the hub it inherited from TWA there in the mid-2000s — left that airport operating far below its capacity. Like at RFD, Allegiant is the only airline with regularly scheduled passenger service at BLV.The full schedule details for all of Allegiant’s 10 new routes are below.Los Angeles International Airport (LAX)
