Updated with Delta confirmation in paragraph two
Delta Air Lines and Korean Air have removed their codes from flights on more than 100 codeshare routes, as the SkyTeam Alliance partners appear to be pulling back their partnership.
Korean Air has removed its code from flights on 97 routes operated by Delta in the USA, Canada and Latin America, while Delta has removed its code from flights on four Korean Air routes - including those between Seattle and Seoul Incheon, which is a route that Delta plans to launch flights on in June 2014 - Delta confirms after being reported by the Airline Route website.
The Atlanta-based carrier said previously that it will end elite frequent flier mile accrual for its frequent fliers on flights operated by the Korean carrier from 1 September.
The airline added that the move does not "signal anything" in terms of its relationship with Korean Air.
The Seoul-based airline will be the only SkyTeam partner where Delta frequent fliers cannot accrue elite mileage.
Korean Air could not be reached for comment.
