Expressjet hubs in Houston, Texas's George Herbert Walker Bush Intercontinental Airport, Newark, New Jersey's Newark Liberty International Airport, and Cleveland, Ohio's Hopkins International Airport. Expressjet operates Embraer ERJ-135's and Embraer ERJ-145's.
In the past, other airlines, such as Trans Colorado Airlines had used the Continental Express name. Trans Colorado Airlines was operating back when Continental had operations in Stapleton Airport in Denver, Colorado. They walked out of Stapleton due to high landing fees. Stapleton had been bulldozed in favor of Denver International Airport.
