Watch out for the seat map for the E190s on copaair.com. If it has no Clase Ejecutiva (E190 V2), it's correct. If it HAS Clase Ejecutiva (E190 V1), the map shows row 18 as the exit row, but it's actually row 17. I'm not sure about the few they have with four across Clase Ejecutiva, as I have always been seated up front on those rare occasions where that lovely configuration has been my flight. That four across thing never shows online, either. Surprise!

It didn't take me long to learn about this error as I sat cramped in behind the exit row in 18C or 18E. Seatguru has it right. IME, even the agents don't know this.

I'm sure they'll fix this someday. It has only been that way for the last 5 years that I am aware of.
