Differences of in-flight food Korean Air & Delta Airlines Business Class

When it comes to dining at Delta One, you are about to taste premium meals cooked from thoroughly selected and fresh ingredients. The menu may differ from one region to another but everywhere, you will find exclusive seasonal options made for you by restaurant chefs. Your dinner will be served on lavish Alessi tableware. There is also a perfect selection of exquisite alcohol available.

The first thing to know about Korean Air business class food is that it was twice the laureate of Mercury Award. So you’re gonna have a very delicious experience as all dishes are made from organically grown ingredients. You can choose from a variety of Western and traditional Asian meals. As for drinks, world-famous wines and champagne are at your disposal.

Onboard entertainment and working options

If you travel business class with Delta, you will be able to explore all the perks given to you by Delta Studio. Each seat in a cabin is equipped with a 110W power outlet and USB ports of different kinds. To watch your favorite movies and shows in HD quality or listen to music, use an adjustable 18-inch screen, the largest among U.S. airlines. Good news: in-flight Wi-Fi is available! You will also receive a noise-restricting headset.

At Korean Air, all seats have 100-150W power outlets compatible with the majority of plug types. You will have a personal LCD monitor to enjoy audio and video on demand. If you are more into reading, they offer the Morning Calm magazine in Korean and English and e-book.

Comparing amenities at business class of Delta Airlines and Korean Air

Delta Airlines provide their clients with TUMI amenity kits that include lip balm, hand and body lotion, earplugs and eyeshades. You will also receive Westin Heavenly bedding accessories: a soft duvet and pillow.

On flights with Korean Air, you get an amenity kit from DAVI only if your trip lasts for more than 6 hours. There are 3 cosmetic items, a toothbrush and toothpaste, and eye mask.


Both Korean Air and Delta Airlines have done a great job in order to help their clients receive amazing onboard experience. Simultaneously, there are quite many differences between two business classes: Delta represents the American approach to comfort while Korean Air attracts customers with its Asian exotics. I would say Delta provides more options onboard since they give every single passenger an amenity kit and bedding set – at Korean Air, they do so only on extra-long flights. Yet the food and drinks are superb at both companies and the entertainment options are equal. Anyway, it is completely up to you which style to prefer!
