American Airlines flight attendants have been selling their seniority to more junior crewmembers for cash. They book trips that they do not intend to take – more desirable trips than what the junior cabin crew could secure on their own – and then they ‘trip trade’.
Flight attendants who do this at American Airlines – mostly legacy US Airways crew – are known informally as “The Cartel.” I shared the note that the flight attendants union sent out, highlighting the practice. American Airlines sent out a warning as well.
