In the final year of DL's MD-11 service from FRA-LAX, my other half and I were the only ones in F. C and Y were full. The three FA's guarded the cabin like guard dogs and wouldn't let anyone up in front. It was by far the best flight I've ever had as we felt like it was our own aircraft. We hope that it happens again.
What a wonderful way to fly 5000 miles.
