Generally speaking only airline ops due to the higher specialisation of an airline role in the eyes of the law. Also there is a shortage of 1500h 121 applicants.... Not part 91 hour builders.
Took a look at Southern Air's pay..... Its up there with the regionals pay. 50hr guarantee at 80 per hour...similar to 50 per hour at a 75 guarantee......
No signing bonus and only $1600 per month as training pay. So less than all regionals....hmmmm
But you get a 737 or 777 rating
So with that in mind it wouldnt surprise me if they are taking aussies.
Oh and based in CVG. Beautiful
