In terms of enjoyment of the job Long Haul at BA is leagues ahead of Short Haul to the extent it’s not even in the rear view mirror anymore.
As for the monitored approach well I’ve got used to it but in reality it’s a tool for low vis. Totally ruins a manually flown visual approach to the extent that it was actually dissuading me from doing them as it was a source of frustration having to then hand it over at 1000 having flown it so well to that point (even more so when they would put the autopilot back in for a few hundred feet just to have to take it out again moments later - yes seriously I’ve seen this done on multiple occasions). I don’t buy the whole both pilots having “skin in the game” argument. If you’re sat there as PM on a multi crew jet transport aircraft and don’t feel a responsibility to be an active party to the operation then you probably shouldn’t be there in the first place. But it’s BA’s train set and I’m not going to pretend it’s something that particularly bothers me now, that’s long since passed.
But you’re going to find a multitude of different opinions on both. These just happen to be mine. Having experienced some of my line training in easy at a regional base I could easily see how that was an attractive avenue for some and every so often (mainly eastbound at 30W) I get a case of the what ifs. Never lasts though.
