Hainan Airlines and China Eastern Airlines were the first to announce that passengers could use mobile phones, tablets and laptops with airplane mode switched on during the whole flight.

海南航空和东航是最先宣布乘客可以在飞行途中使用手机、平板电脑和笔记本电脑的航空公司，但前提是要开启飞行模式。

Later, China Southern, Xiamen Air, Shandong Airlines, Spring Airlines, Lucky Air, Sichuan Airlines, Shenzhen Airlines and Air China, announced in a week that the use of electronic devices is permitted on their flights.

随后不久，南航、厦航、春秋航空、幸福航空、川航、深航和国航，也在一周内相继宣布飞行中可以使用上述电子设备。

National Business Daily reported it costs airlines about 7 million yuan to modify a plane to enable it to provide in-air Wi-Fi services. Industry analysts said because of the limitations of costs, technologies and the number of satellites, they cannot provide a large number of Wi-Fi-enabled flights in the short term.

据《每日经济新闻》报道，在一架飞机上配备空中Wi-Fi，需耗费约700万元。业内分析人士称，由于改装价格昂贵、科技手段不足以及卫星数量有限，尚不能在短期内保证大量航班可以配备空中Wi-Fi。

As of this week, China Eastern has 74 aircraft that are equipped with Wi-Fi, covering its entire international long-haul fleet and more than 160 key domestic routes, with most of them charging fees. All of Hainan Airlines' Boeing B787-9 aircraft are equipped with Wi-Fi services. Xiamen Airlines has limited slots for Wi-Fi connection, with economy class passengers needing to apply for access beforehand.

截至本周，东航的74架客机都已经装备了空中Wi-Fi，覆盖了所有的国际远程航线和160多条国内主要航线，大部分的Wi-Fi服务都是有偿提供。海航所有波音B787-9客机也都提供Wi-Fi服务。厦航则限制Wi-Fi接入人数，经济舱乘客需要提前进行申请。

Industry analysts also said that if airlines equipped Wi-Fi and online payment services, it would help them to sell value-added products, such as duty-free products and paid-for films. Meanwhile, if more flights could install Wi-Fi, it would improve the overall competitiveness of the civil aviation sector, and close the gap between the travel experiences on planes and high-speed trains.

业内分析人士还称，如果航空公司为旅客提供空中Wi-Fi和在线支付服务，还能帮助他们销售增值产品，例如免税商品和付费电影。与此同时，若更多航班安装Wi-Fi，也能提升民航市场的整体竞争力，缩小高铁和飞机在旅行体验上的差异。
