38-year old Jophan Porter has been arrested in Miami on charges of identity fraud.
Police say Porter assumed the identity of Anthony Frair, who lives in New York and claims not to know Porter.
Authorities say Porter is from Guyana, and is in the country illegally.
The FBI and other authorities ware trying to figure out how Porter was able to beat enhanced federal screening rules and get hired as a flight attendant with American Eagle.
American Eagle and American Airlines are owned by the same parent company.
An arrest report said Porter was arrested at Miami International Airport and had several drivers' licenses, a passport and a Department of Transportation identification card with the name Anthony Frair on them.
Reports say the real Anthony Frair was trying to apply for food stamps when he discovered the fraud and alerted authorities.
