Thai Airways International is Thailand's flag carrier, based at Bangkok Suvarnabhumi and a Star Alliance founder. China Eastern Airlines is one of China's big three, based in Shanghai and a SkyTeam member. Travellers compare them for trips between China and Thailand and for connections between Asia and Europe or Oceania.
Both are full-service airlines, so the choice is mostly about network and alliance. Thai suits travellers starting or connecting in Bangkok, or those collecting Star Alliance miles. China Eastern suits anyone flying to or within China, thanks to its many hubs across the country. Check the fare's baggage allowance with either airline before you book.
Thai is built around Bangkok Suvarnabhumi. As of January 2026 it served 51 international and 9 domestic destinations in 29 countries, focused on Europe, Asia and Oceania. China Eastern operates from Shanghai Pudong and Hongqiao, Kunming and Xi'an, with secondary hubs such as Beijing Daxing and Chengdu Tianfu, and lists 232 destinations.
Thai sells Royal Silk (business), Premium Economy and Economy, depending on the aircraft. Seat details vary by aircraft, and a cabin overhaul is planned for 2027. China Eastern's business class varies: narrow-bodies have 2-2 recliner seats, while some A330s have 1-2-1 or lie-flat 2-2-2 layouts. Premium Economy is fitted on all A320neos, A350s, 737 MAXs and 787s. Check the aircraft type for your flight, because both airlines' products differ by aircraft.
Thai allows one 7 kg cabin bag. For tickets issued from 25 November 2025 for travel from 2 March 2026, it reportedly uses piece-based checked allowances: 1 x 23 kg in Economy Saver and Standard, and 2 x 32 kg in Royal Silk. Older tickets keep the weight-based allowance. China Eastern's allowances vary by route and fare, so confirm them on its official site before you book either airline.
Thai serves meals on international flights, with Thai and international dishes that vary by route and month. You can pre-select a meal up to 72 hours before departure. China Eastern includes a complimentary meal in Economy. Selected widebody aircraft have seatback screens, and a July 2026 report says widebody flights now offer free Wi-Fi in all classes.
Thai flew 84 aircraft as of June 2026 with 89 on order. It is moving to a more streamlined fleet and growing its A321neo fleet. China Eastern had 685 aircraft in service in December 2025 with 291 on order, including the Comac C919, for which it was the launch customer. Cirium reported 79.29% on-time arrivals for Thai in June 2025. China Eastern's Flight MU5735, operated by subsidiary China Eastern Yunnan, crashed in March 2022.
Thai belongs to Star Alliance and runs Royal Orchid Plus, with Royal Orchid and Royal Silk lounges. China Eastern belongs to SkyTeam and runs Eastern Miles, with Silver, Gold and Platinum tiers. Eligible passengers can use SkyTeam lounges. Shanghai Airlines and China United Airlines also take part in Eastern Miles. Your existing miles account, and the partners you fly with onward, should decide this.
Neither is better overall. Thai is the better fit for Bangkok-based and Star Alliance travellers, and China Eastern for China itineraries and SkyTeam members. Compare the actual aircraft and fare on your date.
Under the piece-based system for tickets issued from 25 November 2025, Economy Saver and Standard reportedly include 1 x 23 kg and Royal Silk 2 x 32 kg. Older tickets keep the weight-based allowance, so check your fare.
Economy includes a complimentary meal. A July 2026 report says widebody flights offer free Wi-Fi in all classes, and selected widebody aircraft have seatback entertainment.
