I’m 190cm so for sure worth booking for me. That said I have had situations before (pre-covid) where I’ve booked these/similar seats and the front few rows of “premium economy” end up being stuffed but there’s rows upon rows of empty seats at the back of the plane and felt a bit sheepish about spending the extra money when I could have moved to a free row.

At T-48 the seats are free for Enrich Platinum - possibly for OneWorld Emerald too but chargeable otherwise. Checkin or gate agents very reluctant to give a freebie move on the day in recent times
