More reliable: Shanghai Air or China Eastern? (TYO - SHA)

Question

It looks like nonstop prices and departure times are similar. Should I choose Shanghai Air or China Eastern for travel from TYO to/from Shanghai? Please share your experiences with both airlines. thanks for your help.

Answer

When choosing between Shanghai Airlines (a subsidiary of China Eastern) and China Eastern Airlines for a nonstop flight from Tokyo (TYO) to Shanghai (SHA), here is a detailed comparison based on reliability, service, and traveler feedback.

1. Reliability & On-Time Performance

China Eastern is one of China’s major carriers and has a broad international footprint. Some travelers report that flights are generally reliable, though delays of 30-60 minutes are not uncommon.
Shanghai Airlines, while smaller, benefits from being part of the China Eastern group. Some reviews suggest decent service, though fewer data points exist.

2. Service Quality & Passenger Experience

China Eastern: Reviews are mixed. On TripAdvisor it averages around 3/5. Issues often raised include cramped seats, limited in-flight entertainment, and inconsistent customer service.
Shanghai Airlines: Smaller sample size, though some reviewers rate it at 7.5/10 for certain flights. Passengers liked cabin crew and comfort, but noted less choice in entertainment.

3. Route Fit & Practical Considerations

Since your route is Tokyo to Shanghai, check which airport in Shanghai you land at—Shanghai Airlines often uses Hongqiao (SHA) or Pudong (PVG), and China Eastern may also operate from either. Ensure compatibility with your onward travel plans.
If you value slightly better service and less crowding, Shanghai Airlines may have an edge (though still modest). If you prioritise alliance benefits (e.g., SkyTeam) or greater schedule flexibility, China Eastern might be advantageous.
Check the exact aircraft type, seat pitch, WiFi/entertainment availability and baggage allowances—these vary more than airline brand in many cases.

4. My Recommendation

If I were choosing between the two, I would lean toward choosing Shanghai Airlines on this route—assuming the timing and price are comparable—because of slightly better passenger feedback for comfort and service, and because you specifically mention Tokyo–Shanghai (an international short-haul flight) where the difference in service may matter more. You will still get a solid routine flight experience with China Eastern, but you may sacrifice a little on comfort.

Summary:

Choose Shanghai Airlines if the price and schedule match and you value comfort and calmer service.
Choose China Eastern if you prefer more schedule options, or if loyalty/loyalty-programme benefits matter.

Whichever you pick, book early, check aircraft/seat configuration, and plan for typical boarding/check-in times in Japan and China.
