Possibly not enough airbus pilots at Jet2 yet for any of them to be reading this? As far as I remember in the 737 part B hand flying is encouraged, with a caveat about busy airspace etc. I know it’s there but it’s not a big deal. Generally the PF will say that they would like to hand fly to or from a certain point and the PM says yes, or no if there’s a good reason (airspace/weather etc). I would guess that the airbus part B will be the same, taking into account any manufacturers guidance that I don’t know as I’ve never flown one. But generally in J2 hand flying is encouraged, or has been on all the flights I’ve done in nine years in the company.
