It was definitely the east bound ATL -> LGW, and not our west bound return LGW -> CVG.

DL added a flight to London, and changed our original flight (I think it was flight 10 to LGW to much earlier in the morning), and assigned flight 8 to basically replace flight 10 in the afternoon. When I noticed the schedule change and called Delta, they offered to rebook me on any other flight, but I decided against taking the earlier flight.

The food on the west bound return was good, my son especially enjoyed the lobster bisque, even though they made him wait over 30 minutes to "cook" it while the rest of the BE cabin have already finished their dinner.
