They will serve dinner. My suggestion is to eat at a nice restaurant if you have time before your flight. Skip the very underwhelming D1 meal and get some sleep.

That meal at 1:30am ATL time will be at lunch time in Korea. It’s one way to start changing your body clock right away.

In my experience, D1 meals have been okay to not-so-great. I ordered the Korean Meal on this flight. Has anyone tried it? While I don’t expect it to be as good as the Japanese meal, it seems like it should be better than the regular D1 options.

I just flew this route and you do get a full dinner. There is also a mid flight meal a snack and a breakfast. It’s such a long flight that you don’t have to worry about finding time to sleep or having enough to eat.

I had the Korean meal and it was from a local Atlanta restaurant and was quite good. Short ribs and some fish soup.

This is hardly abnormal. In fact in many ways I find it helps me begin adjusting my body clock to the new time zone on the westbound redeyes, at least if in J. Flights to Australia from the West Coast usually leave late (around midnight). On flights to Australia, dinner is served after takeoff, which from the time it’s actually served until you finish is about 2-3 hours into the flight, forcing me to stay up and fall asleep as close as possible to a more normal “bedtime hour” at the destination Sometime after dinner and dessert, then head to sleep for about 7-8 hours. Not long after waking up, breakfast is served and then you’re landing at a normal morning hour at the destination. This is how it went for me when I flew LAX-BNE on VA and I had very little jet lag at all upon arrival (less than I feel going eastbound in the US and trying to adjust my body clock to the earlier wake up call).

As another example on that same trip I flew AKL-SIN on NZ, which departed AKL at 1AM and arrived at SIN around 6 AM. Dinner was served after takeoff from AKL on that flight.

Don't forget that there's always the option to skip meal or to request that it be served to you all at once, on one tray, so that you can eat more quickly and gon to sleep.
