不少飞往第三国的旅客会在中国中转。要不要过境签、能不能出机场、行李要不要重新托运、留多少时间够，取决于你持的是不是联程客票、在中转机场怎么安排。本文按国家移民管理局、民航局和机场的公开口径逐条说明。
- 过境免签适用条件：24小时过境免签适用于所有国家的公民和中国所有对外开放口岸，条件是持有效国际旅行证件和已订妥座位的联程国际机票（或者船票、车票），在中国境内停留不超过24小时且不离开口岸限定区域。240小时过境免签目前适用于57个国家，可从24个省（自治区、直辖市）的65个对外开放口岸入境，持普通护照和已订妥座位、确定日期的联程客票，停留不超过10天。
- 不同机场的转机流程：联程客票（同一客票号码）旅客通常按机场的中转指引走中转通道，一般不需要提取行李；非联程旅客在中转过程中需要提取行李，重新办理值机和安检。如果两段航班停靠不同航站楼，需到中转柜台咨询并乘坐机场的中转摆渡车。
- 行李是否直挂：能否直挂取决于客票是否为联程、承运航司之间是否有行李直挂协议。非联程客票由各航段独立承运，行李一般要在中转地提取后重新托运。建议在始发站值机时就和航司确认行李能否直挂到最终目的地。
- 留多少时间够：各机场、各航站楼的最短衔接时间不同。以上海浦东机场公布的口径为例，同一航站楼内国际转国内、国际转国际的最短衔接时间约为75分钟，跨航站楼约为90分钟。初次中转、需要提取行李或者跨航站楼的旅客应留出更长时间，建议至少预留3小时以上。
- 能不能出机场：适用24小时过境免签的旅客不得离开口岸限定区域；确需离开的，应当先向口岸出入境边防检查机关申请办理临时入境手续，临时入境期限不超过15日。适用240小时过境免签的旅客，可以在规定区域内从事旅游、商务、访问、探亲等活动；工作、学习、新闻报道等仍需事先批准并办妥相应签证。
- 误机怎么办：非联程客票的各航段互不影响，误机后的改签、退票和费用由旅客与相应航司按其运输总条件处理；联程客票按承运人的运输总条件办理。建议保留行程单、登机牌等凭证，一旦发现衔接时间不足，第一时间联系航司或者机场中转柜台。
出发前建议确认四件事：客票是不是联程（是否为同一客票号码）、行李能不能直挂到最终目的地、中转机场的航站楼有没有变化、是否需要过境签。把两段航班的中转衔接时间算进去，如果需要跨航站楼，还要预留摆渡和安检的时间。
区域性入境免签补充：除过境免签外，中国还实行区域性入境免签政策，例如61国人员入境海南、停留不超过30天免签，外国旅游团乘坐邮轮入境、停留不超过15天免签，东盟国家旅游团入境云南西双版纳或者广西桂林、停留不超过6天免签等。各类政策的适用国家、口岸和活动范围不同，出行前请以国家移民管理局最新公布为准。
两点提醒：过境免签不等于免签入境，离开限定区域或者超时停留都可能被认定为非法居留，建议严格按照客票和入境许可的时间与范围安排行程。本文为一般性说明，具体政策、口岸范围和衔接时间以国家移民管理局、民航局及机场官方最新公布为准。
以上为一般性说明，具体要求与最新规定以官方发布为准。

Layovers in China: Do You Need a Transit Visa and Can You Leave the Airport?
Many travellers heading to a third country connect through China. Whether you need a transit visa, whether you can leave the airport, whether you must re-check your bags and how much time to allow all depend on whether your ticket is a through ticket and how the connecting airport is set up. This guide walks through each point using published information from the National Immigration Administration, the civil aviation authority and airports.
- Who qualifies for visa-free transit: the 24-hour visa-free transit policy applies to nationals of all countries at all open ports in China, provided you hold a valid international travel document and an onward international flight, ship or train ticket with a confirmed seat, stay in China for no more than 24 hours and do not leave the restricted area of the port. The 240-hour visa-free transit policy currently applies to nationals of 57 countries, who may enter through any of 65 open ports in 24 provinces, autonomous regions and municipalities, holding an ordinary passport and an onward ticket with a confirmed seat and departure date, and stay for no more than 10 days.
- Connecting at different airports: passengers on a through ticket (a single ticket number) usually follow the airport's transit signs and normally do not need to collect their bags. Passengers on separate tickets must collect their baggage during the connection and check in and go through security again. If the two flights use different terminals, ask at the transfer desk and take the airport's inter-terminal shuttle bus.
- Whether bags are checked through: this depends on whether the ticket is a through ticket and whether the airlines involved have a baggage interlining agreement. Separate tickets are carried independently by each segment, so bags normally have to be collected and re-checked at the connecting point. It is worth confirming at the departure airport whether your bags can be checked through to the final destination.
- How much time to allow: minimum connecting times differ by airport and terminal. At Shanghai Pudong International Airport, for example, the published minimum connecting time is about 75 minutes for international-to-domestic and international-to-international transfers within the same terminal, and about 90 minutes when changing terminals. First-time transfer passengers, those who must collect bags, or those changing terminals should allow more, and at least three hours is a sensible buffer.
- Whether you can leave the airport: travellers using the 24-hour visa-free transit policy may not leave the restricted area of the port; if you genuinely need to leave, you must first apply to the port's exit-entry border inspection authority for temporary entry procedures, and temporary entry is limited to no more than 15 days. Travellers using the 240-hour visa-free transit policy may engage in tourism, business, visits and family reunions within the permitted areas; work, study and news reporting still require prior approval and the appropriate visa.
- If you miss your connection: with separate tickets, each segment is independent, and rebooking, refunds and costs are handled by you and the relevant airline under its general conditions of carriage; with a through ticket, the carrier's general conditions of carriage apply. Keep your itinerary, boarding passes and other documents, and contact the airline or the airport transfer desk as soon as you see that the connection will not work.
Before you fly, confirm four things: whether your ticket is a through ticket (a single ticket number), whether your bags can be checked through to your final destination, whether the terminal at the connecting airport has changed, and whether you need a transit visa. Factor the connecting time between the two flights into your plans, and if you need to change terminals, allow extra time for the shuttle and security.
A note on regional visa-free entry: beyond visa-free transit, China also operates regional visa-free entry policies. For example, nationals of 61 countries may enter Hainan without a visa for stays of no more than 30 days; foreign tour groups arriving by cruise ship may enter visa-free for no more than 15 days; and tour groups from ASEAN countries may enter Xishuangbanna in Yunnan or Guilin in Guangxi visa-free for no more than 6 days. The eligible nationalities, ports and permitted areas differ by policy, so check the National Immigration Administration's latest announcements before travelling.
Two reminders: visa-free transit is not the same as visa-free entry, and leaving the restricted area or overstaying can be treated as illegal residence, so plan your trip strictly within the time and area allowed by your ticket and entry permission. This article is general guidance only; for specific policies, ports and connecting times, refer to the latest official information from the National Immigration Administration, the civil aviation authority and the airports.
