[7] Asiana's formation did not come about as a policy initiative favoring liberalized market conditions, but rather because of pressure from other chaebols and interests that wanted to compete.

In 1990, Asiana began its first scheduled international services, to the Japanese cities of Tokyo, Nagoya, Sendai, and Fukuoka.

On 28 January 2003, the airline became a full Star Alliance member, expanding its worldwide network and global brand.

[13] Asiana began to focus on being an environmentally friendly company in the mid-1990s, leading to decisions such as completely banning in-flight smoking and cigarette sales in 1995.

[14] In 2001, Asiana Airlines was recognized for being the "first environmentally friendly company within the service industry" by the South Korean Ministry of Environment.

[14] Some of Asiana's other environmentally minded programs include an emissions measurement and reduction system; reducing pollution from ground facilities; and partnering with the Rainforest Alliance for coffee served on board.

Apart from this prestigious title, the company has received the Best Airline for Onboard Service and Flight Attendants for eight consecutive years, among other awards.

[19] In June 2019, Aekyung Group, the parent company of Korean low-cost carrier Jeju Air, was considered as a strong candidate to take over.

[21] Asiana Airlines discontinued unprofitable routes throughout July 2019 to October 2019, including Seoul–Incheon to Chicago–O'Hare, Delhi, Khabarovsk and Sakhalinsk.

[26] AeKyeong Group, the parent company of Jeju Air, has expressed interest in acquiring Asiana Airlines.

[27] On 4 September 2019, Aekyung Group, Mirae Asset Daewoo, and Korea Corporate Governance Improvement applied a letter of intent to acquire Asiana Airlines.

[28] On 12 November, a consortium of HDC Hyundai Development Company and Mirae Asset Daewoo was selected as the preferred bidder.

In July 2020, HDC Hyundai Development Company received approval from Russian authorities for its acquisition of Asiana Airlines.

In August 2021, the Malaysian Aviation Commission approved the merger between Korean Air and Asiana Airlines, citing economic efficiencies and social benefits.

[39] On 16 November 2021, it was announced that Ministry of Industry and Trade of Vietnam had approved Korean Air's acquisition of smaller local rival Asiana Airlines Inc.[40] On 26 December 2022, the Ministry of Commerce of the People's Republic of China announced its approval of Korean Air's business combination with Asiana Airlines.

[49] On 12 December 2024, Reuters reported that Korean Air has announced the completion of the purchase of the debt-laden Asiana Airlines in a deal worth 1.5 trillion won (US$1.6 billion).

[4] The airline's head office moved from Hoehyeon-dong, Jung District to Asiana Town in Osoe-dong on 1 April 1998.

The airline serves several gateway cities in North America and Europe while retaining limited coverage of Oceania.

Passengers in these classes are offered pyjamas, souvenirs, and "amenity kits" containing items such as skin creams, toothpaste, eye shades, and earplugs.

Miles accumulated in the program entitle members to bonus tickets, class upgrades, and other products and services such as dining at Outback Steakhouse.
