If you mean "flight attendants", the people on the plane who help you, it's "la tripulacion" for the crew, el aeromozo (male) or la aeromoza (female.) You may also see the word "azafata", the equivalent of "stewardess". The pilot is "el piloto".
If you really mean "flight attendance", it would be "asistencia del vuelo"- the attendance of the flight.
