Ratings: routesandmiles.com/ratings
Delta uses its premier A350-900 aircraft on SLC-ICN, with 190 seats in Delta Main (Economy), 36 seats in Delta Comfort, 48 seats in Delta Premium Select and 32 suites in Delta One with lie-flat beds. Economy seats offer a reasonable 31-32 inches of seat pitch.
International Delta Main (Economy) meal service features a three-course menu and a full selection of alcoholic and non-alcoholic beverages, including spirits.
The timing of the outbound flight isn’t ideal in terms of minimizing jet lag (the mid-morning departure makes for an extra-long day), but it’s handy for connecting to onward flights such as Korean Air’s flights to Bali. Returning to Salt Lake City, the evening departure time is better for encouraging sleep and helping passengers get readjusted to US Mountain time.
