When Laura runs away from her wedding, her hair is very light brown. Later the same day in the diner, her hair is platinum blonde.
When we see Maggie (Christina Ricci) in the Village at the episode's beginning, her hair is wavy and falls below her shoulders. When she arrives at the airport 35 minutes later, her hair is straight and bobbed.
Maggie is given a helicopter ride from the helipad atop the Pan Am building to Idlewild Airport. The opening establishes the time of these events as 1963. Helicopter service from the Pan Am building did not start until late December 1965, more than two years later.
The issue of Esquire Magazine distributed on the first flight has Henry Wolf's cover design - "The Americanization of Paris". This design was made for Esquire in 1958 (the September Issue), so they would not have been giving this out in 1963.
The aircraft in Cuba during the Revolution is identified as a Douglas DC. However, it has four-bladed propellers. Thus, it is a Douglas DC7.
At the Havana airport, a parked Douglas C-47 transport plane can be seen in the paint scheme of the U.S. Army Air Forces in mid 1944, complete with bold black-and-white "invasion stripes" applied for D-Day. However, the scene takes place around 1960, years after the Army Air Forces had been subsumed into the newly-formed U.S. Air Force and most of these aircraft had been sold to civil airlines. With the rare exception of an aircraft being used for a Hollywood war movie, no C-47 would have 1944 Army paint by this time; most had long since been repainted to reflect their new ownership.
When they arrive at the London hotel, you can see signs for an MTA bus stop and a US style One Way road sign.
When Maggie first enters the aircraft she goes directly into the cockpit. The flight crew is surprised to see her despite the fact that she had to walk several yards directly past the windscreen and in full view of the flight crew in order to get to the aircraft.
Karine tells Laura that the Clipper Majestic is brand new and has never been flown.
However, the aircraft would have undergone at least one flight, i.e. to the airport where they both board the plane.
