The last of the flowbacks have been downgraded to First Officers because their start date at Eagle no longer allows them to hold bid status as a Captain. Under the agreement, flowbacks were given "golden" seniority numbers which allowed them to hold jet captain in equipment of their choice. The golden numbers are gone because flowback is gone.
AMR had something to gain by the Miami flying, not this. If they are trying to get extra pilots off the property they will want them completely off the property. If pilots can flow back to Eagle thus displacing an Eagle FO into furlough they save 20K instead of a properly-compensated AA FO
