Well, as it's name would suggest the answer is 'A'.

On a related note my mother-in-law was a sky goddess for Philippine in the 50's. She flew on a DC-3 her entire career. When she got married she transferred to the ticket counter. She was first based in Manilla, then Rome and finally Honolulu where she went to the ticket counter. Before she was 30 she had been around the world several times visiting all the exotic and glamorous cities of the world.
