I flew on Korean Air B747-8 from Atlanta to Seoul Incheon in First Class. This is currently the longest Boeing 747 flight in the world with an average flight time of 15-16 hours.

My seat was 2A in the nose of the 747. Check out the Korean Air First Class Suite (Kosmo Suite II) and its amenities.

The aircraft registration was HL7636, a 7 year old B747 manufactured in 2015.

We push back on time and with a short taxi to Runway 27L for takeoff.

Flight time was 15 hours 11 minutes which is rather short considering some days this flight takes over 16 hours due to the strong headwind on Westbound and no Russian airspace overfly. Here is the current route map without flying over Russia.

After takeoff, flight service started promptly. I went to Economy Class to see the meal preparation. There is Korean bibimbap across all classes from First to Economy. The other choice was beef in red wine sauce. The meal tray size was huge, I am glad to see Korean Air didn't cut corners in Economy as many other airlines serve you a smaller tray with an optical illusion of having more food on the tray.

First Class Dining

The First Class dining experience on Korean Air is phenomenal. There are 7 courses like the proper First Class service.

The meal was huge, possibly the biggest portion I've ever had in First Class. I noticed the tablecloth and dish-wear were getting quite old. Interestingly, Korean Air does not have a service plate to enhance the dining experience. The table was huge but the dishes were too small in the proportion to the table.

The efficiency of Korean Air crew was a huge plus. They managed to serve 6 First Class passengers full lunch within 2 hours.

We crossed the Canadian border and continue heading toward Alaska and the Pacific Ocean.

The Rest of the flight

After full lunch, it is time to shut eye and rest. The Korean Air Kosmo Suite II can convert into a fully enclosed suite. There is plenty of space and width on the seats making this a larger First Class suite than others.

Row 1A and 1J are the most private pair seats in First Class right up the nose. While Row 3A and 3J have the biggest separation due to the 747 curvature. There are no bad seats in First Class.

At around mid-flight, I ordered a Korean Ramen. This is officially the best in-flight snack I've ever tried. It is warm and tasty which makes your body feel comfortable and sleepy again! There is spicy and non-spicy version.

The rest of the flight was spent watching IFE. I particularly enjoyed the KALMAN vlog which features Korean Air staff (they call them KALMAN) showing behind the scenes at their job.

Korean Air 747-8 has a fairly outdated IFE and does not have Wi-Fi connectivity yet which is becoming a necessity for 15 hours+ flights. Before arrival dinner was served about 2 hours prior to landing, I had the beef bourguignon but it was fairly dry.

We landed about 30 minutes ahead of schedule. The total flight time was 15 hours and 10 minutes. Watch the landing on my video.

For many of us, the journey itself is the most exciting part of the travel. Korean Air B747-8 First Class is one fine example of luxury travel with a fully enclosed private suite, fine dining, amenities and attentive service. The only thing missing is the Wi-Fi connectivity to make the experience perfect.

Currently, Korean Air flies the 747-8 between Incheon and Atlanta, New York JFK and Honolulu.
