Plot hole: When it's learned that Jonah has taken a flight to New York by himself, the panicked adults never think to contact United Airlines, the New York Police Department, port authorities, airport security, the taxi companies, or the Empire State Building staff to alert them that an unaccompanied minor child is headed their way. Instead, Sam hops on the next flight to NYC to search for Jonah by himself. Considering the many hours Jonah waits on the Empire observation deck alone, it is apparent that none of the above knew he was there.
