It seems that more and more airlines are upgrading and opening new lounges around the world quicker than ever before—from Qantas’ new Heathrow and Melbourne lounges, Virgin Australia’s lounge in Hong Kong, to Air New Zealand’s lounge in Melbourne Airport, and United Polaris Lounge in Chicago.

The more recent ones are Korean Air’s first class, business class, and frequent flyer lounges located in Incheon International Airport, Terminal 2. They have been strategically built and positioned inside the terminal to allow travelers to check-in, pass through security, and board seamlessly and efficiently.

And the best part? Each upper class gets its own special area for the best traveler experience. Let’s take a look at each one a little more closely.

Those flying in First Class can experience exclusivity in a premier lounge with limited seating. Because the lounge is designed for the most high-paying passengers, the space can only seat a maximum of 30 travelers.

Most of the chairs are designed with privacy in mind, with a curved back “wall” surrounding a chaise—perfect for those who want to take a few minutes and get some shut-eye before a flight.

Flying in business class? You will have the option to relax, catch up with work, and enjoy a meal at one of two Korean Air Business Class Lounges—one with 200 seats and the other with 400 seats.

These two spaces will feature general amenities that you would find in most other lounges, including free Wifi, drinks, liquors, snacks, hot and cold meals, ample space and A/C adaptors to charge up your devices.

If you’re a Korean Air Morning Calm Premium and Million Miler Club member, then there’s a separate lounge for you as well. The red and neutral tones give this area a sophisticated and modern feel, something you would expect from any members-only lounge.

Named the Miler Club Lounge, this exclusive space will also be available to SkyTeam Elite Plus members.

Those who are flying in business or first class on one of the SkyTeam airline alliance such as Delta Air Lines, Air France, and KLM, will also have access to the new Korean Air lounges (excluding the Miler Club Lounge).
