I was inclined to decline to opine on yet another thread about recline, but what the heck, let's anyway.
And the reason for my reluctance? There is no right answer, only each person's opinion and preference.
Mine, FWIW, is:
I don't recline on flights to NZ, or any domestic flights
I may well recline on longer flights if overnight or other sleep-conducive conditions (e.g. v long sector), but even then, sometimes not utilise the entire recline
I would never recline during meal service and wouldn't mind being woken to go upright if already asleep when such a service commenced
Whilst I dislike people reclining in front of me on short (< 4 hours) sectors, its the airlines that put the functionality there, not the pax.
I cannot recall anyone remaining inclined in front of me during meal service, but I think I could convey to them the importance of them returning to upright without too much difficulty.
I have copped (on a trans-tasman flight) one of the reclining bookreaders mentioned above. Not only that, when they had finished reading they remained inclined and attempted to place the book under their seat, straight onto the top of my resting feet (where they had previously placed a newspaper, which I subsequently had kicked into the aisle). A good swift (but non-injuring
) kick to the depositing hand ensured the book did not remain there.
