French Kiss (1995) on Netflix

Kate and Charlie have a perfect life planned out before them: buying a house, marriage, kids, the whole works. Kate's fear of flying keeps her in Canada while Charlie goes to Paris for a medical convention. While there Charlie is smitten by the lovely Juliette. He calls off the wedding with Kate and she nervously boards a plane to get him back. She ends up sitting next to the petty French thief Luc Teyssier. He hides a stolen necklace and smuggled grape vine in her bag to get it through customs. Her bag is stolen, the necklace apparently lost, and Kate and Luc head to Cannes -- Luc to find the necklace and Kate get Charlie back. Along the way, Kate and Luc begin having feelings for each other -- which change the course of their lives.
