The analyst rating from Citi Research for Trip.com Group (TCOM.US) and TONGCHENGTRAVEL (00780.HK) was maintained at "Buy" due to the positive performance in passenger throughput during the Spring Festival travel rush. The report highlighted a 4% year-over-year increase in total passenger volume, with particularly strong growth in the first four days of the holiday, where total volume rose by 6.8% year-over-year. This strong performance across various transportation modes (railway, airline, roadway, and waterway) contributed to the optimistic outlook and the decision to keep the ratings at Buy, along with target prices of US$82 and $28, respectively.
