I believe there are 6 rows of 2-2-2 (although one row may not be a full row?)

On time - I have flown Lan on approx 6 RTs to/from the US, within South America a few times, and within Chile on many flights, and I had 2 sizeable delays, total. One was a late arriving aircraft to LAX (2 hour delay), and the other was a fire near SCL shutting down ops due to the smoke (similar delay). Any other delay that I've had was unremarkable. I did notice a couple of longer delays on other flights while at SCL last week.
