Charter flight on I think a 737 JFK - ELH. It was to Club Med and I was with my family and siblings with their families. We totaled 19 people and there was one other family of 4. That was it, entire plane to ourselves. FA's were great especially since more than half the passengers were kids under the age of 16. They let the kids spread out and have their own rows and served them breakfast and soda's the entire time.
