Hi
I'm due to fly with LATAM on their 787-9 (SCL - IPC) and have a pretty much free choice of seat in economy. "Space+" appeals given its such a small premium for what is a 5.5hr flight. but question is - which seat is best?
Has anybody flown this plane / route and can advise?

Row 12 seems to offer benefit of no seat in front of you to recline on to your lap, but:
- in row 12, is IFE screen on the bulkhead wall in front of you, or in the arm rest? (reducing seat width)
- do you in fact benefit from more legroom in rows further back (13 - 16) as you gain the space under the seat in front of you?
- "Space+" is advertised as having footrests, is this the case in row 12? (as they are usually attached to the seat in front of you, and row 12 faces the bulkhead)

Any tips appreciated!
