there are going to be so many aircraft types....
777-200LR and 777-200ER... 767-400ER,300ER,300... 757-200,200ER,300... 737-800,700,200... MD-88... MD-90...A319, A320, A330, 747-400, 747-200 charter, DC9-30,40,50 and then! 787.
are we all going to have to go through an expanded timeframe such as initial again(they cant train people in a few days on so many aircraft types)?? can you imagine yearly required HOT?? the size of your manual??
It would make sense to me anyway to divide the training and qualifications based on region. if a FA is based in the North Region(DTW BOS NYC) they are trained on the aircraft deployed/based at that region and so on...if a FA successfully transfers to a South region(ATL...ext) or another region.. they receive additional training on aircraft that may not be based in another...
or simply maintain qualifications based on aircraft that is assigned at a single base and if a FA chooses to transfer to another receives training based on that aircraft assignment..at that base.
you know??
