During the flight to England, Al makes a disparaging comment about the in-flight movie, Dutch (1991). Ed O'Neill (Al) played the titular character in that movie. Another joke at the movie's expense is made in Dial 'B' for Virgin (1994), where the movie is given away for free.
When the Bundys arrive at the airport, there is a person holding a sign in the background with the last name: Leavitt. Another person holds a sign that says Moye. This is a reference to Executive Producers Ron Leavitt and Michael G. Moye (who also wrote the show). Not as obvious is a third person holding a sign for Anderson. John Maxwell Anderson is one of the producers, as well.
