The reporter shown at the airport is named Ofelia Baquero. Guillermo del Toro - being one of the directors and writers - gave a nod to Pan's Labyrinth (2006) by giving the reporter that name. The lead character in Pan's Labyrinth (2006) is named Ofelia who is portrayed by the actress Ivana Baquero.
Jonathan Hyde's character is named "Eldritch Palmer." This appears to reference the Philip K. Dick novel "The Three Stigmata of Palmer Eldritch."
