I do not understand what the whole fus about 170 is? Great to have order of new aircrafts, it's always a good sign, but to choose company based on the type they fly is crazy.(my opinion)
121 jet time is 121 jet time.
I personally came to xjt so I can fly with experienced captains on the type, not the guys trying to figure it out after flying it for 300-1000h in some cases.
For me that 170 award would probably not be a welcomed thing.
