为了省钱，不少人把两段航班分开买（即自行中转）。这种方式票价可能更低，但行李要自己重新托运，衔接不上时也要自己承担后果。
- 与联程票的区别：联程航班是指旅客预订在同一个客票号码上的两个及以上航班（即使是不同航空公司的航班）；非联程航班由承运航空公司分航段分别独立出票，通常存在两个或以上的运输合同。
- 行李需重新托运：非联程票的行李一般不能直挂，需要在中转机场先提取行李，再重新办理值机、托运和安检；即使是联程票，也建议向航空公司确认托运行李能否办理直挂。
- 最短衔接时间：以上海浦东机场为例，同一航站楼国内转国内最短衔接时间为 60 分钟、国内国际互转为 75 分钟、国际转国际为 75 分钟；不同航站楼（T1 和 S1、T2 和 S2）分别为 75 分钟、90 分钟、90 分钟。
- 误机责任归属：非联程航班两个航班独立存在、互不影响，若其中一段发生调整（包括非自愿的航班取消、延误、超售等）导致另一段无法正常乘坐，另一航班的乘坐和退改签规则不变，相关费用需由旅客自行承担。
- 是否值得省钱：非联程票往往票价更低，但需要自行承担误机风险、行李重新托运的时间成本，以及可能的过夜住宿与改签费用；行程紧、行李多或首次来华时，省下的钱可能不足以覆盖风险。
- 购买建议：为两段之间预留充足衔接时间，优先选择同一航站楼中转，为两段都选择可退改的客票，必要时购买涵盖中转误机的旅行保险，并在出发前核对中转地的入境与过境要求。
还需要注意两点。其一，联程航班的行程在未发生非自愿变更的情况下须按顺序出行，例如预订了广州—北京—沈阳，如果广州—北京段未使用，北京—沈阳段也不可使用。其二，部分在线旅游平台会把不同航班的组合当作一个产品出售，下单前请确认是否为联程航班。
如果中转地是中国境内机场，还要确认是否需要办理入境手续、以及是否需要提取行李后重新安检。行李较多或携带需申报物品时，建议把衔接时间放宽到 3 小时以上，并为两段航班分别保留订单凭证，以便出现问题时向各自的出票航空公司申请处理。
以上为一般性说明，具体要求与最新规定以官方发布为准。

Self-Transfer Flights in China: Baggage and Missed-Connection Risks
To save money, many travellers book two separate flights, known as a self-transfer. Fares can be lower, but you must re-check your own baggage and bear the consequences yourself if the connection fails.
- Difference from a through ticket: a connecting (through) flight means two or more flights booked under a single ticket number, even if operated by different airlines. A non-through itinerary is issued segment by segment by the operating carriers, usually involving two or more separate contracts of carriage.
- Baggage must be re-checked: with a self-transfer ticket, baggage generally cannot be through-checked, so you must collect it at the transit airport and re-check it and go through security again. Even with a through ticket, it is worth confirming with the airline whether baggage can be through-checked.
- Minimum connecting time: at Shanghai Pudong International Airport, for example, the minimum connecting time within the same terminal is 60 minutes for domestic-to-domestic, 75 minutes for domestic-international transfers and 75 minutes for international-to-international; between different terminals (T1 and S1, T2 and S2) the times are 75, 90 and 90 minutes respectively.
- Who bears a missed connection: the two flights of a self-transfer itinerary exist independently and do not affect each other. If one segment is changed (including involuntary cancellation, delay or overbooking) and you cannot take the other, the boarding and refund/change rules of the other flight remain unchanged, and the related costs are borne by the traveller.
- Is it worth the saving? Self-transfer tickets are often cheaper, but you take on the risk of a missed connection, the time cost of re-checking baggage, and possible overnight accommodation and change fees. On a tight itinerary, with lots of baggage, or on a first trip to China, the saving may not cover the risk.
- Booking tips: leave ample connecting time between the two segments, prefer transfers within the same terminal, choose refundable or changeable fares for both segments, consider travel insurance that covers missed connections, and check the entry and transit requirements of your transit point before departure.
Two further points are worth noting. First, a through itinerary must be travelled in sequence unless an involuntary change occurs: for example, if you book Guangzhou–Beijing–Shenyang and do not use the Guangzhou–Beijing segment, the Beijing–Shenyang segment cannot be used either. Second, some online travel platforms sell combinations of different flights as a single product, so confirm before booking whether it is a through itinerary.
If your transit point is an airport in China, also confirm whether you need to clear entry formalities and whether you must collect your baggage and go through security again. With heavy baggage or items that need declaring, it is advisable to allow more than three hours for the connection and to keep the booking records for each segment so that you can approach each ticketing airline if problems arise.
The above is general guidance only. For specific requirements and the latest rules, please refer to official announcements.
