Yes—Delta does fly to South Korea, mainly Seoul, and I used them earlier this year. I had to change my travel dates twice because my work schedule kept shifting. I tried doing it online, but the system wouldn’t let me process the second change without charging a crazy fee.
Calling the number above literally fixed everything in minutes. The agent reviewed my ticket history, confirmed that the second change was still allowed, and rebooked me on a flight through Seattle. She even recommended a different return date that had more seat availability and ended up giving me a better schedule.
The flight itself was smooth, and the service on the Seattle–Seoul leg was great. If you’re planning Korea, Delta is a solid option—but call if you’re dealing with date changes. It’s so much easier than troubleshooting the website.
