A domestic flight is useful when it saves meaningful door-to-door time, reaches a route with poor rail connections, or connects naturally with another flight. It is not automatically faster than high-speed rail. Compare:
- travel from the hotel to the departure terminal
- required check-in and bag-drop time
- security and terminal walking
- scheduled flight time and disruption risk
- transfer from the arrival airport to the final address
Then compare the same components for rail. A two-hour flight can produce a longer travel day than a centrally located train.
Build a Door-to-Door Comparison
Use a worksheet rather than intuition:
| Segment | Flight | Train |
|---|---|---|
| Origin transfer | Hotel to the correct airport terminal | Hotel to the correct railway station |
| Pre-departure process | Check-in, bag drop, security, gate | Identity check, security, platform access |
| Main journey | Scheduled flight plus possible holding | Scheduled train |
| Arrival process | Taxiing, bags, terminal exit | Platform to station exit |
| Final transfer | Airport to destination | Station to destination |
Check the exact airport and station names. Large cities can have multiple airports and multiple stations far apart.
Book With the Travel Document You Will Carry
China’s 2025 guide for foreign visitors says domestic air tickets can be booked through airline websites, apps, mini programs, ticketing platforms, or at an airport. It also notes that change and refund fees depend on airline policy.
Enter the passenger name, passport number, nationality, and other identity fields exactly as the booking channel instructs. Do not invent a domestic ID number or shorten a name merely to make a form accept it. If the system cannot represent the passport name correctly, contact the airline or seller before paying.
Keep the original passport used for the booking available on travel day. If the passport was renewed or lost after booking, ask the airline how the document change must be handled.
Identify the Operating Airline
A seller, marketing airline, and operating airline may not be the same. Record:
- ticket number and booking reference
- seller and its support channel
- operating airline and flight number
- departure airport and terminal
- baggage allowance for the purchased fare
- change, refund, and no-show terms
For a codeshare, confirm check-in and baggage rules with the operating carrier. A generic statement on an aggregator page may not control the actual flight.
Baggage Rules Are Fare-Specific
Do not assume that a low fare includes checked baggage or that all airlines share the same cabin limits. Open the fare conditions and operating airline’s dangerous-goods page. Check:
- cabin-bag dimensions and weight
- checked-bag allowance
- excess-baggage charges
- liquids, aerosols, and sharp items
- spare lithium batteries and electronic devices
- medicine and mobility equipment
Keep essential medicine, identity documents, valuables, and one charging route in the cabin bag when permitted. Never place a spare lithium battery or power bank in checked baggage unless the operating carrier and applicable rule explicitly allow it.
Power Banks Need Special Attention
The Civil Aviation Administration of China announced that, from June 28, 2025, passengers on domestic flights may not carry power banks without a CCC marking, with an unclear CCC marking, or from recalled models or batches. Read the current CAAC notice and the airline’s current guidance before packing.
Inspect every power bank rather than assuming a familiar brand is accepted. The CCC restriction is separate from capacity, quantity, terminal-protection, and in-flight-use rules. A product can fail more than one test. If its label is damaged or the model is recalled, leave it out of the trip.
Check-In and Airport Timing
Use the airline’s published cutoff, not a universal arrival-time slogan. Work backward from the cutoff and add time for:
- traffic to the correct terminal
- passport-based check-in or manual document review
- checked baggage
- security queues
- a long walk or shuttle to the gate
Online check-in may be unavailable for some foreign-passport bookings or may still require document verification at the airport. A mobile boarding pass does not remove the need to meet the airline’s document and baggage requirements.
At Security
Prepare to remove or present items as instructed. Keep power banks and spare batteries accessible for inspection. Do not argue from another country’s rule; ask the officer or airline how the current domestic rule applies.
If an item is rejected, request the available options. Depending on the airport and item, that may mean surrender, disposal, returning it to someone outside security, or another procedure. Do not conceal it in another bag.
When the Flight Is Delayed or Cancelled
Separate four questions:
- What is the new operating status?
- What rebooking or refund does the ticket rule provide?
- What immediate assistance does the airline offer?
- What will the insurer reimburse and what evidence is required?
Use the airline’s official channel and the original seller. Save notifications, boarding documents, receipts, and the time support was contacted. Do not purchase a replacement before understanding whether doing so affects a refund or insurance claim.
If the delay threatens an international connection booked on a separate ticket, contact the onward carrier immediately. Separate tickets usually create more self-managed risk than a protected through itinerary.
