- This is the sixth episode with the same title card as the previous five episodes.
- The episode's ending where Clarence and Chad go into the plane's cockpit would be impossible by today's airliner safety standards as the cockpit doors are now locked since the 9/11 attacks on the Twin Towers of the World Trade Center and The Pentagon. The position of the plane at the end (as it goes down the clouds) resembles the position of United Airlines Flight 175 as it hit the South Tower.
- The episode's ending itself can also be uncomfortable to some viewers following the crash of LaMia Flight 2933 in Colombia in late 2016, resulting in the episode to barely have any reruns following the tragedy.
- John Waters guest stars in this episode as Captain Tom.
- A similar plot from this episode would later be used in the We Bare Bears episode, "Baby Bears on a Plane".
- The plane on the title card is a Boeing 747 despite the plane in the episode being a cartoon depiction of a Boeing 737.
- This episode reveals that Mary gets sick from a plane ride.
- Mary's mother Dilliss Wendle has died, and the family is going to her funeral in Florida.
- This episode revealed that Chad has aerophobia, a fear of flying, especially on airplanes.
- This is the ninth episode which does not feature Jeff and Sumo, the first eight were "Zoo," "Rise 'n' Shine," "Patients," "Goose Chase," "Dust Buddies," "Hurricane Dilliss," "Chalmers Santiago," and "Where The Wild Chads Are."
- Music sounding like "Varanasi Sunrise" from the 1992 film Baraka is played during some scenes.
- The man Clarence sits with resembles George Costanza from Seinfeld.
