Yes, it is nice, especially when compared to the 767s. Of course, it is double edged sword -- F gets off after J class. Ideally, LAN would deplane through the forward doors and then move the jetway back to the L2 door for boarding.

BTW, how full was F? If not full from LAX, did it fill-up in Lima?

I am asking b/c I currently have the center seat reserved, but would prefer the window for the departure from LAX. Last time, I had 1A and was by myself for the LAX-LIM flight, but had a neighbor for the LIM-SCL leg (I do not like sleeping next to a stranger and, IMO LAN's divider b/w seats doesn't do much). Had I taken the center seat as my assignment, I could have enjoyed 1A from LAX and then switched to the center seat for the full segment.

I am gambling on it not being full and me being able to grab the window from LAX and move to middle when it fills in LIM.
