The next phase of Delta Air Lines’ joint-venture agreement with Korean Air has begun, with the US carrier officially launching its new daily non-stop service between its hub at Hartsfield-Jackson Atlanta International Airport and Seoul’s Incheon International Airport.

The route adds to Korean Air’s existing daily service between the two hubs, operated by the carrier’s B777-300ER. Delta is flying its B777-200LR on its route, set up with 37 lie-flat seats in Delta One, 36 seats in Delta Comfort and 218 seats (laid out 3-3-3) in economy.

Notably, compared to its Korean counterpart, Delta is bringing in-flight wifi to the route (Korean Air doesn’t offer wifi on board any of its aircraft – see why here).

As part of the agreement, Korean Air is also due to add additional flights to its Los Angeles and San Francisco services starting this summer.;
