Frontier is not available, but is listed
Response from developer
Thank you for your feedback. The airline dropdown is included during account creation to identify interest from flight attendants at other airlines and to prevent unsupported users from completing registration. My Flight Pay currently supports only American Airlines flight attendants, and selecting Frontier displays that availability message before an account is created. We understand how the airline list could suggest broader availability and are reviewing the wording to make its purpose clearer. Happy flying!
