The captain goes back and tells the woman that her assigned seat is in coach. Again, the blonde replies, "I'm young, blonde and beautiful, and I'm going to sit here all the way to New York."
The captain doesn't want to cause a commotion, and so returns to the cockpit to discuss the blonde problem with the co-pilot. The co-pilot says that he has a blonde girlfriend, and that he can take care of the problem.
He then goes back and briefly whispers something in the blonde's ear. She immediately gets up, says "Thank you so much," hugs the co-pilot, and rushes back to her seat in the coach section. The pilot and flight attendant, who were watching with rapt attention, together ask the co-pilot what he had said to the woman.
He replies, "I just told her that the first class section isn't going to New York."
