Flew IAD-CDG-LHR in 2000/01 on AF.
I was quite disappointed to be honest, they could have at least handed out some champagne
- nope! Coach was less than half full!
The Captain didn't even mention anything !!
As the flight left around 8.00pm US time, most probably the crew had celebrated the New Year (Paris time) even before boarding the flight
No, Didn't see any fireworks at FL370
Mind you, I flew out on Christmas day and AF did hand out Santa shaped chocolates which I thought was a nice touch - hence my above expectation on the New Year's eve flight.
