Six Days Seven Nights (1998)

Plot:

Taking a romantic tropical island week off with her boyfriend, an ambitious, decisive New York girl agrees to help her magazine out by covering a story on a neighboring island. The only plane available is piloted by a laid-back heavy drinker with whom she shares a mutual dislike. But she has no choice and he can't refuse the money. When the plane crash-lands on an uninhabited island with little chance of rescue they both wish they had made other arrangements - at least to start with.
