China Eastern, Air China and Spring Airlines can all be sensible choices for a domestic China itinerary. The best one is usually not decided by a brand label alone. It depends on the exact flight, the airport, the fare bundle, your baggage and how much flexibility you need.
For foreign visitors, the most useful comparison is the same route on the same day. Search the actual flight numbers and read the operating carrier’s fare and baggage rules before paying. A low fare can stop being low once you add checked baggage, a seat, airport transfer or a change fee.
The quick way to choose
Choose the flight that gives you the best total journey rather than the lowest first number.
- Air China may be a strong fit when its schedule, airport or connection works best for your trip. Check the operating carrier when a ticket is code-shared.
- China Eastern can be a practical option on its available routes, particularly when the times and airport suit your hotel or onward travel.
- Spring Airlines is often attractive when you travel light and the basic fare genuinely meets your needs. Its baggage rules make a careful fare-bundle comparison especially important.
This is not a reliability ranking. Operations, weather, aircraft changes and airport congestion vary by day. Compare the exact ticket conditions presented at checkout.
Baggage is where the comparison becomes real
On many mainland domestic routes, Air China’s official baggage page describes a 20 kg free checked-baggage allowance for economy passengers, with higher allowances for business and first class; it also says domestic routes use a weight-based system. Read Air China’s baggage guidance.
China Eastern’s official allowance page similarly lists 20 kg for economy and premium economy on domestic flights, with 30 kg for business and 40 kg for first class, subject to its stated conditions. Read China Eastern’s current baggage allowance.
Spring Airlines publishes fare-package-specific rules. Its current English terms say SpringSaver has no free checked baggage, while checked-bag allowance can depend on the package purchased; it also lists a standard carry-on allowance of one piece up to 7 kg and 20 × 30 × 40 cm for SpringSaver and SpringFlexi, with different allowance for SpringPlus. Read Spring Airlines’ terms.
Policies and fare packages can change. Treat these official pages as a starting point, then use the allowance displayed on your own booking as the final purchase check.
Compare the fare bundle, not only the cabin label
| Check | Why it matters |
|---|---|
| Total price after extras | A cheap base fare may exclude baggage or seat selection. |
| Airport and terminal | The cheapest flight may cost more time and money to reach. |
| Checked and carry-on baggage | Your suitcase can determine which ticket is truly cheaper. |
| Change and refund rules | A fixed plan and a flexible plan have different value. |
| Operating carrier | The operator’s rules matter on a code-share flight. |
| Arrival time | A late arrival may mean a more expensive transfer or hotel. |
If two tickets cost nearly the same after extras, choose the one with the less stressful airport journey and rules you can accept.
Think about airport geography
Beijing and Shanghai each have more than one major airport, and many large Chinese cities have airports far from central districts. Check the route from your accommodation to the departure terminal and from the arrival airport to your next stop. A one-hour difference in airport transfer time can outweigh a modest airfare saving.
For an international-to-domestic connection, confirm whether the flights are on one protected ticket or separate bookings. Separate tickets can mean you carry the risk of a missed onward flight if the first segment is late.
Fare flexibility and travel-day preparation
Read voluntary-change and refund conditions before payment, especially around holidays or if your rail connection or visa timing might move. Air China notes that its airline rules can be supplemented or overridden by ticket-use conditions for particular fares, which is a good reminder to read the conditions of the actual ticket—not a general web summary. Air China’s current conditions of carriage.
Use the passport details exactly as they appear in the document you will show at the airport. Save the booking reference, recheck terminal and flight status on travel day, and give yourself adequate time for baggage drop and security.
