I've got a flight LIM - CUZ - LIM coming up, and was wondering what side of the plane would be best for good views. I thought I had read someplace that the left side of the airplane was best LIM - CUZ, and the opposite on the way back. I wanted to confirm that this is true.

Also, I called up LanPeru to get a window seat on the left side of the airplane LIM - CUZ, and the agent gave me 11J. This seem strange to me because I think most times the airlines letter the seats from left to right, so a seat on the left hand side of the airplane should be 11A, not 11J. I asked the agent about this, and she assured me she was looking at the seating map and that 11J was on the left hand side. I have my doubts, however. Thoughts?
