从美国到中国，直飞能省下十几个小时的折腾，但可选的城市对并不算多。先搞清楚哪座城市有直飞、由谁执飞、要飞多久，再决定是买直飞还是接受一次转机，往往比直接搜票价更省钱。
- 中国一侧主要航点：北京（首都、大兴）、上海浦东、广州、深圳、厦门、成都，部分航季还有福州、武汉、重庆、青岛等城市。
- 美国一侧主要航点：洛杉矶、旧金山、西雅图、纽约肯尼迪、底特律、达拉斯，以及芝加哥、华盛顿杜勒斯、波士顿等。
- 执飞航司：中方为国航、东航、南航、厦航、川航、海航；美方为美联航、达美、美航。同一城市对通常只有一到两家执飞。
- 飞行时长：飞西海岸约 11 至 13 小时，飞东海岸约 14 至 16 小时；向东飞顺风更快，回程逆风更久，具体看航路、季节与机型。
- 班次频率：按航季编排，热门城市对多为每日班，其余为每周多班，增班与减班通常在换季时公布，购票前以航司当季时刻表为准。
- 转机对比：经首尔、东京、中国香港转机往往票价更低，但要多一次起降、行李可能需自提再托运，并要确认是否需要过境签证。
- 淡旺季票价：暑期（6 至 8 月）与春节前后最贵，9 至 11 月和深冬相对便宜；提前一到三个月订票，舱位和日期选择都更多。
中美之间的直飞运力还没有回到疫情前的水平，这意味着同一座美国城市可能只有一家中国航司执飞，或者只有一条中国航点。如果你的目的地不在直飞名单上，比较现实的方案是飞到北京、上海、广州再转国内航班，或者经第三地中转。
转机方案要算清三件事：行李能不能直挂到最终目的地、中转地是否需要过境签证、误机后是否有后续航班可以改签。票价便宜两三千元，但要在中转地多花五六个小时甚至过夜，对带老人小孩的家庭未必划算。
订票时注意姓名拼写与护照完全一致，国际段和国内段最好出在同一张客票上，行李额度按国际段标准执行；如果分开出票，中转时可能要重新托运并重新安检。
以上为一般性说明，具体要求与最新规定以官方发布为准。

Nonstop Flights from the US to China: Routes and Flight Times
Flying nonstop from the US to China saves more than ten hours of connections, but the number of city pairs served is still limited. Knowing which cities have nonstop service, which airlines fly them and how long the flight takes usually saves more money than starting with a fare search.
- Main gateways in China: Beijing (Capital and Daxing), Shanghai Pudong, Guangzhou, Shenzhen, Xiamen and Chengdu, with Fuzhou, Wuhan, Chongqing and Qingdao served in some seasons.
- Main gateways in the US: Los Angeles, San Francisco, Seattle, New York JFK, Detroit and Dallas, plus Chicago, Washington Dulles and Boston.
- Airlines: Air China, China Eastern, China Southern, XiamenAir, Sichuan Airlines and Hainan Airlines on the Chinese side; United, Delta and American on the US side. Most city pairs have only one or two carriers.
- Flight time: roughly 11 to 13 hours to the West Coast and 14 to 16 hours to the East Coast. Eastbound flights are faster with tailwinds; the return leg takes longer, depending on routing, season and aircraft.
- Frequency: schedules follow the aviation season. Major city pairs usually operate daily, others several times a week, and increases or cuts are announced at season changes. Check the airline's current timetable before booking.
- Connections compared: routing via Seoul, Tokyo or Hong Kong, China is often cheaper, but adds a landing, may require collecting and re-checking bags, and needs a transit visa check.
- Peak and off-peak fares: summer (June to August) and the weeks around Chinese New Year are the most expensive; September to November and deep winter are cheaper. Booking one to three months ahead widens both seat and date choices.
Nonstop capacity between the US and China has not returned to pre-pandemic levels, which means a given US city may be served by only one Chinese carrier, or connected to only one Chinese gateway. If your destination is not on the nonstop map, the practical options are to fly into Beijing, Shanghai or Guangzhou and connect domestically, or to route through a third country.
When comparing connections, work out three things: whether bags can be checked through to the final destination, whether the transit point requires a transit visa, and whether a later flight exists if you misconnect. A fare that is a few hundred dollars cheaper can cost five or six extra hours, or an overnight, which is rarely worth it with children or elderly travellers.
When booking, make sure the name matches your passport exactly, and try to keep the international and domestic legs on one ticket so the international baggage allowance applies. On separate tickets you may have to reclaim and re-check your bags, and go through security again.
The above is general guidance only. For specific requirements and the latest rules, please refer to official announcements.
