Dean takes on his first assignment since his promotion, piloting the Clipper Majestic on its inaugural New York to London flight. Bridget is supposed to be his lead stewardess, until she's a no-show for the flight. Grounded purser Maggie is called in to fill in for her. On the same fateful flight, Kate adds another dimension to her work as she takes on her first assignment from U.S. intelligence. Her stress is compounded when she discovers that newly minted stewardess, Laura, her sister, is also working the same flight.

Sparks fly between Laura and a sailor on a special – and unusually wild -- Pan Am flight bringing servicemen home, leading Laura to realize what she’s really looking for in a man, as well as opening her eyes to the malicious racial climate in the country. Meanwhile Kate’s complicated mission to turn Niko to work for the U.S. government culminates in dramatic fashion, threatening their personal relationship.

Ted asks Laura to help him make a woman from his past jealous; a dangerous mission puts Kate and Anderson in jeopardy; Maggie clashes with a congressman; Colette meets Dean's parents.
