I want to move my trip to Feb just to enjoy the vibe on the plane, pretty sure you don't need a nanny Irine!
I do recall a trip from Chicago to MoBay a few years ago when 3 Russian national couples (based on their clothes, jewelry and attitude, I think they were pretty rich) were being very obnoxious and rude to the flight crew, especially in the last hour when they were cut off from the booze... I was very happy to see all 6 of them invited separately into those cute little chat rooms behind immigration.
