I should clarify, regionals spend significantly more time on the basics of 121 operations (the flight release was just an example). Not to say that other carriers don’t go over flight releases at all. That was poorly worded and I apologize.

Having a 250 hour ab initio students and whether they’re successful in a A320 isn’t the argument by any means. Europeans definitely proved that it can be done. What I’m trying to say is that those specific airlines do not have a training program outline that would be conducive for a cessna driver.

UA had CFIs going to the right seat of a A320/B737 with little success pre-covid. I don’t know the specifics, but I heard the failure rate was high and the program was short lived.

To bring this back around, ULCCs usually don’t have the training program to allow someone that is new to the 121 world to be as success as the others with 121 experience. That’s expected, that’s all.
