Delta adds free Wi‑Fi on Korea routes

Delta Air Lines (DAL) has begun offering free in-flight Wi-Fi on trans-Pacific routes serving South Korea, extending its complimentary connectivity across Asia-Pacific services. The rollout covers Pacific routes linking the United States with Asia-Pacific markets including South Korea, turning in-flight internet on Korea–U.S. routes from a paid add-on into a standard service.

The free in-flight internet, branded Delta Sync Wi-Fi, is provided in partnership with U.S. telecom operator T-Mobile. Passengers who enroll for free in the SkyMiles loyalty program can use the connection on personal devices such as phones and laptops for web browsing, social media and video streaming during the flight.

With the expansion to Asia-Pacific routes, Delta now provides free Wi-Fi across international routes on six continents. Around 1,300 of its aircraft are equipped with Wi-Fi, representing more than 95% of the airline’s fleet, enabling broad access to the service throughout its network.

Once connected, passengers can access the Delta Sync digital platform, which offers in-flight entertainment, travel information and partner content. Available content includes articles from The New York Times and The Wall Street Journal, films and series from Paramount+, and live sports coverage such as Formula 1 through Sport 24.

Alongside the Wi-Fi expansion, Delta is relaunching its Fly Delta mobile app and introducing a Korean-language version to better serve customers in South Korea. The revamped app supports route searches, bookings, check-in, mobile boarding passes, real-time flight information, baggage tracking, flight changes and cancellations, as well as SkyMiles member services.

The updated app also features an AI-based assistant called Delta Concierge, now available with Korean-language support. This AI concierge is designed to handle key customer inquiries and is part of a broader effort to enhance digital travel services for domestic passengers in Korea.

Korean Air and Asiana Airlines introduced free Starlink-based in-flight Wi-Fi on September 15, offering the service on selected aircraft regardless of cabin class. Korean Air began with three A350-900s and one B777-300ER, while Asiana Airlines started with nine A350-900s and one A330-300.

Both Korean carriers plan to extend free Wi-Fi to their entire fleets by the end of 2027. With Delta now providing free Wi-Fi on its Korea-linked trans-Pacific services and completing coverage on its international network, competition in complimentary in-flight internet on the Korea–U.S. corridor has intensified.
