Korean Air and Hawaiian Airlines have expanded their partnership by bringing their two frequent flier programmes together under a fully reciprocal agreement.
Members of Korean Air's Skypass and Hawaiian Miles can now earn miles on all flights operated by both carriers. They can also redeem their miles for tickets on either carrier.
Previously, Hawaiian and Korean Air had established a code-share agreement for passengers travelling around Hawaii or South Korea. Then Korean Air launched a direct Incheon-Honolulu service on January 12 of this year.
These moves reflect a deepening relationship between Hawaii and Korea due to a surge of business and leisure travel between the two countries. The Hawaiian Tourism Authority stated last year that visitors from Korea grew by 69 percent.
