The FBI estimates the boy was unconscious for most of the flight, which reaches altitudes of 38,000 feet, according to Simon.
The boy was in good condition medically, Simon said, although he was disoriented when he was discovered by airport employees.
In a statement, Hawaiian Airlines said personnel "noticed the individual on the ramp after the flight's arrival and immediately notified airport security."
"Our primary concern now is for the wellbeing of the boy, who is exceptionally lucky to have survived," the airline said.
The boy will not be charged, according to Simon.
Airport officials say the 16-year-old boy scaled a perimeter fence at the California airport while it was dark.
San Jose airport spokeswoman Rosemary Barnes said on Monday the boy remained undetected as he crossed the airport ramp and entered the wheel well of Hawaiian Airlines Flight 45. Barnes says the airport's security exceeds federal requirements, but no system is 100 percent secure.
The flight left Sunday morning for Maui. The FBI says the boy hopped down from the wheel well when the plane landed at the Maui airport and was seen wandering the airport grounds.
He was questioned by the FBI, but then released to child protective services. He wasn't charged with a crime, but San Jose police say they will review whether charges are warranted.
