The Charles De Gaulle Airport is the largest international airport in France.
A couple days after the Louvre Museum incident, Walter Peck led Peter Venkman, Ray Stantz, and Winston Zeddemore through the Charles De Gaulle Airport while declining to answer their questions about what the next case was about. Peck only told Winston the situation was sensitive and considered it a personal favor if he left it at that. They took a flight to Shannon Airport in County Clare.
- In Ghostbusters International #7, page 1, Walter Peck's pose and his line is reminiscent of Uncle Sam in the famous "I Want You!" poster for military recruitment.
- In Ghostbusters International #7, page 2 panel 1, there is a sign for Lucien Airlines near Peck. This is a reference to Monsieur Lucien from The Real Ghostbusters episode "The Ghostbusters in Paris"
