So after much anticipation I was again able to fly the DL 772 since they have again put it on the ATL-LAX-ATL route once daily. see this link for my last experience in dec:
Last time I flew there was obviously an issue with the engines syncing or something which caused an extremely annoying "buzzsaw" (vibrations & noise) effect throughout the flight. However this time it was smooth as butter. my medallion upgrade did not clear but when I checked in I was number 3 on the standby list for bizelite with 5 seats open so I knew my chances were good. ended up getting 10J which, according to seatguru, was tagged yellow with limited legroom. I am a tall person so this had me a bit worried, but ended up to be just fine. it didnt have as much legroom as other bizelite seats, but I did not find it intrusive in the least.
So, the flight was great. great sunset at FL380. great service. and I dont know if it was because it was bizelite service, but the food was definitely an upgrade from the normal DL first meals. probably just coincidence. so overall, it ranked in my top 5 flights, Id have to say. I made sure to thank the f/a's that served me on the way out. great flight! keep it goin' delta!
