About Japan Transocean Air Co.

Japan Transocean Air (JTA) is a Japanese regional airline based in Okinawa, known for its domestic services and close affiliation with Japan Airlines.

Japan Transocean Air (JTA) was established on June 20, 1967, initially operating as Southwest Air Lines. The airline rebranded to Japan Transocean Air in July 1993 and operates as a subsidiary of Japan Airlines (JAL), focusing on services within Japan. Its primary operational base and main hub are located at Naha Airport in Okinawa, Japan.

JTA's fleet primarily consists of Boeing 737-800 aircraft. As of recent data, the airline operates a fleet of 14 Boeing 737-800s, with an average age of 8.6 years. The airline's route network is predominantly domestic, connecting Okinawa with various key Japanese cities and islands, particularly within southwestern Japan and the Ryukyu Islands. JTA is set to launch its first scheduled international service between Okinawa (Naha) and Taipei (Taoyuan) on February 3, 2026. As an affiliate of Japan Airlines, JTA is a member of the Oneworld global airline alliance.

For passenger comfort, JTA offers Economy Class and a premium domestic product called Class J. Class J features wider leather seats and headrest covers adorned with Okinawa's traditional dyed Red Mold design, providing enhanced comfort and legroom. In-flight services typically include a selection of complimentary hot and cold beverages and in-flight magazines. Some flights also provide Wi-Fi access, though browsing performance may vary.

Safety Information

Japan Transocean Air maintains a strong safety record, boasting an unblemished history of zero accidents involving human fatalities since its inception in 1967.
