I have a few flights on Latam domestically in Peru all on A320 planes.

When we select seats the LATAM website shows row 13 as the exit row with "more than 17cm extra legroom" and that is what we have booked.

However Seat Guru, Seat Maestro etc. all show row 12 as the exit row with extra legroom. I know that these sites are often out of date, but I just wanted to check if anyone has any experience and can confirm that the Latam site is correct and row 13 is the best to book?

We would prefer not to have a bad surprise when we come to the plane.
