Why does the latest advert for pilots list the 747 and not the 777 fleet? Is the 747 Freighter lifestyle so undesirable that they need to hire directly onto the fleet and not the 777 fleet? I realise that the 777 fleet has great route variety and layovers. Can pilots bid across fleet types (i.e., from 777 to 748F or from Airbus to Boeing) or are they limited to one fleet type? Why would a pilot not want to bid onto the 748F fleet?
