The second window exit was not boarded up on the ER during reconfiguration... When only one exit row shows up, you must be looking at the Gulf version.
The actual aircraft that will fly the leg is not nailed down until approx. 48 hours before departure of the outbound flight. Soooooooooo... if you're flying from Nice to JFK and want to know exactly what type of 767 you'll be on... check to see what type of a/c flew the JFK-NCE leg the day before... that's the a/c you'll be on.
