Delays and Rescheduling: What to Do When Flights and High-Speed Trains Have Problems

First, Look at the Probabilities

• Flights: The on-time rate of domestic flights in China is about 75–85%. It drops significantly during summer thunderstorms (June–August) and winter fog, smog, or snow days (December–February). Delays are most common at the four major hubs: Beijing, Shanghai, Guangzhou, and Shenzhen.
• High-speed Rail: Extremely high on-time rate (over 95%), but service may be suspended during extreme weather (typhoons, heavy snow).

Prevention

• Choose early flights: Delays at Chinese airports tend to accumulate, and flights from 6–8 a.m. have the highest on-time rates; the later the flight, the worse it tends to be.
• Do not schedule important events on the arrival day: Schedule only rest on the arrival day; this is a basic rule of itinerary design.
• Allow enough transfer time: For domestic-to-international transfers, allow more than 3 hours; for transfers between airports, allow 4–5 hours.
• Buy delay insurance: Most insurance policies and some credit cards provide this; the claims process for flight delay insurance in China is already quite smooth.

When Delays Occur

Flights

1. Confirm the source of information: Only rely on the airline’s official app, SMS, or airport announcements; do not believe third-party reporting.
2. Rebook immediately: Once a delay is confirmed, rebook another flight through the app as soon as possible; the sooner you choose, the more options available. Waiting until you are at the airport often leaves only late flights.
3. Rights: If a delay is caused by the airline and exceeds 4 hours, most airlines provide meals and accommodation; for force majeure events (weather), they usually only assist with arrangements, no compensation.
4. Delay certificate: Request a "Flight Delay Certificate" from the airline; it is required for insurance claims.
5. Complaints: Civil Aviation Service Quality Supervision hot line in China 12326.

High-speed Rail

1. If the train is canceled, you can get a full refund on 12306 (including already issued paper tickets, which need to be processed at the window).
2. If you miss a train, you can rebook another train on the same day within 2 hours after departure.
3. Typhoons and heavy snow suspensions will be announced in advance, so pay attention to the announcements on 12306 and at stations.

Refund and Change Rules

High-speed Rail

• More than 8 days before driving: no handling fee.
• More than 48 hours: 5%.
• 24–48 hours: 10%.
• Within 24 hours: 20%.

Flights

• Varies greatly by airline; generally, ticket cancellation more than 24 hours before departure incurs a fee of 5–20%, within 24 hours 20–50%.
• Special fare tickets (below 30–40% of regular price) are often non-refundable and non-changeable; check carefully when purchasing.

Practical Tips

• Keep flexibility in your schedule: schedule return flights for the evening of the last day, not the afternoon.
• Arrive one day before important milestones: if catching an international flight or attending an important event, arrive in the hub city one day in advance.
• Backup plan: check the high-speed rail schedule on the same route; if the flight is canceled, high-speed rail is often a more reliable alternative (e.g., Beijing–Shanghai 4.5 hours).
• Overnight at the airport: Beijing Capital, Shanghai Pudong, and Guangzhou Baiyun all have pay-per-use lounges and nearby hotels (most provide shuttle service).
