I booked seat 34G on their A350-900 through Delta.com last week and was impressed that it includes two full-size checked bags, priority boarding in Zone 2, and standard Comfort+ seat selection. The fare books into 'E' class which earns full SkyMiles and MQMs, unlike their stripped-down $826 basic economy option that restricts carry-ons and seat assignments.
While Singapore still edges out Delta slightly on food quality and champagne selection, Delta's new Seoul service matches them on seat pitch (34") and recline (5"). The main drawback is that Delta's basic economy at $826 feels unnecessarily restrictive compared to Korean Air's similar fare class that at least includes one checked bag. For premium cabin travelers, I'd recommend spending the extra $260 for regular economy to avoid basic economy's limitations, especially on such a long transpacific route.
