Love Is in the Air (2013) on Netflix

Plot summary

Antoine practices law in New York, and he needs to get to France for the last stage of a job interview. The seat next to his on the plane is taken by Julie, the woman he was involved with three years earlier in an affair that ended badly. She is days away from her wedding to Franck, and the two of them have seven hours of flight ahead in close quarters, so conversation is unavoidable. Fellow passengers hear the story of the couple's past as Antoine and Julie recount it: how they met, their first date, the difficulties between them, the marriage they once planned. Their memories disagree, and each version leaves out what the other supplies.
