China Airlines said it will launch its first New Year themed flight, with an Airbus A321neo operating the designated Taipei–Bangkok flight CI837 on December 31, allowing passengers to welcome 2027 in the air. Sales open at 10:00 on November 5 through the airline's website and app.

Passengers on the themed flight will receive a NT$1,000 Uber credit for airport transfers, an elephant key ring from the Tourism Authority of Thailand, a limited-edition New Year blind-box bear co-branded with Aroma Teddy, a free three-day unlimited-data KLOOK eSIM, onboard celebrations and a New Year certificate, plus a draw for China Airlines miles, a Pikachu-liveried CI2 model aircraft and other merchandise. For dining, all cabins can choose barbecue from the大腕燒肉restaurant, while economy class also gets a Thai-style grilled chicken leg rice, along with desserts and drinks designed for the themed flight.

On arrival in Bangkok, passengers will receive a free Bangkok BTS transit card and ChaTraMue Thai tea, and can enjoy Divana SPA at a discounted price; stays at華航好哩宿partner hotels can be partly offset with miles.
