I am taking a group of 8 on the JFK-MEX flight in a few weeks in J. We booked out the 6 seats in the mini cabin and 7D/F for the remaining 2 seats. Wish we could have fit all 8 of us in the mini cabin as I think it would have been a blast. I put a married couple in front of us so they can just stare at each other the whole flight while we make the self-service bar our own.
I'll report back after the flight and let ya'll know how it goes.
