Homer manages to escape the airport disguised as Bibendum, the Michelin tire company mascot.
In Paris, Lisa is dressed as Madeline, a character from a French book and TV series of the same name.
Homer, when talking to a policeman, states that "our family is falling apart like your European Union". This is clearly a reference to the UK EU referendum, in which the UK would vote to leave the European Union. This episode was broadcast in May 2016, just one month before the EU referendum was held in the United Kingdom on 23 June 2016; in which 17.4 million people voted to leave and 16. 1 million voted to remain.
The flying balloon house seen is a reference to the 2009 Pixar film Up.
The characters Cesar and Ugolin previously appeared in Season 1, Episode 11 The Crepes of Wrath. Although they have appeared in other seasons, this is the first time in 26 years since 'The Crepes of Wrath', in which they don't have a minor appearance.
César and Ugolin are the names of two of the main characters from Marcel Pagnol's novel collection "L'Eau des collines" which consists of "Jean de Florette" and "Manon des Sources".
There's no "E33" gate on the Charles de Gaulle Airport, the airport used as inspiration to the one in this episode. However, this may have been done intentionally, to keep Springfield's location in the United States a secret.
The plane seating plan is not on any plane.
When the Simpson family arrives at the Charles de Gaulle Airport they are in the departure lounge.
