a young blonde woman on a flight to darwin in second class suddenly got up out of her seat and walked to first class and promptly sat down

upon seeing this the stewardess chased her up and said "madam would you kindly revert to your allocated seat"

to which the girl said "I'm blonde and I'm beautifull and I deserve first class to Darwin"

in order not to cause a scene in first class the stewardess went back and got the senior steward who also asked her to shift to her allocated seat with the same response "I'm blonde and I'm beatifull and I am flying first class to Darwin" 

the head steward said "enough of this" and went and got the co-pilot

the co-pilot came to first class, bent down and whispered something in the womens ear

the woman got up with a "hrrrrmmphhh!! well why didnt you say so" and returnd to her seat

all the stewardesses were amazed and asked the co-pilot what he had said

he said that he had told the young lady that "first class does not go to Darwin on this particular flight"
