An overwhelming majority of business travelers are now members of frequent flier programs operated by the airline industry. This article addresses relevant ethical issues, particularly employee perceptions of ethical issues, in such programs. A structured questionnaire technique, supported by personal interviews, was used to gather insights into frequent flier practices and attitudes. A fundamental conclusion of the research is that (1) significant ethical dilemmas are posed by frequent flier programs, (2) employees and employers generally choose to ignore these ethical dilemmas, (...) and (3) employee perception of the ethical issues in frequent flier programs is not significantly influenced by employee attributes such as education level, salary, organizational position, age or sex. Recommendations are offered to reduce the inherent ethical dilemmas in frequent flier programs. (shrink)
