A Rednote post recently sparked discussion and jokes among netizens after showing a notice stating that "Air France-KLM does not accept portable air conditioners as checked or carry-on baggage," against the backdrop of extreme heatwaves in Europe this summer and the difficulty of securing one in European markets. 
Air France-KLM customer service later confirmed to the Global Times on Monday that the restriction was in place, explaining that passengers' baggage must comply with relevant rules and requirements, which are established based on operational and safety considerations.
The discussion came as Europe has been hit by persistent extreme heat in recent months, triggered widespread heat alerts and a surge in local demand for air conditioners, a product that was not widely installed in European households.
After the RedNote post was released, some netizens shared similar experiences in the comments section, with one writing: "I just bought six small fans to take to Germany as gifts, [now that] Air conditioners are out of the question. But it seems the heatwave is finally over."
Some speculated that the sign was put up after travelers to Europe tried to imitate a widely reported case in which a Chinese employee based in Shanghai helped a French colleague visiting China on a business trip bring an air conditioner from China back to Europe by air in July.
The story was shared by the Chinese employee on RedNote. After researching different models, the Chinese selected a compact unit suitable for international transport based on its size and weight. The air conditioner reportedly used non-flammable R410A refrigerant, with a refrigerant charge of 350 grams, and contained no lithium battery. According to the post, the netizen concluded that the unit could be transported as regular baggage transport rather than being treated as dangerous goods.
The netizen also carefully consulted the ICAO technical instructions and IATA dangerous goods regulations to determine whether the air conditioner needed to be handled as dangerous goods, per the post.
The French colleague, with sufficient baggage allowance, only paid for additional packing services. The total cost came to 1,412 yuan ($209.26), including 1,260 yuan for the air conditioner, 130 yuan for airport packaging, and 22 yuan for a high-power European power adapter.
The French passenger was reportedly transported the air conditioner successfully and arrived in Barcelona.
However, airlines have reminded passengers that while some air conditioners may qualify for checked baggage, strict requirements still apply.
Battery and refrigerant restrictions must be followed, as portable air conditioners containing lithium batteries are strictly prohibited from being checked in. Meanwhile, size and weight limits must be considered as the equipment must comply with airline baggage allowances, which typically limit individual pieces to 23 kilograms or 32 kilograms, and total dimensions generally not exceeding 158 centimeters. 
Professional packaging is also recommended, with travelers advised to use airport packing services to reduce the risk of damage during baggage handling. 
Experts said that as Europe continues adapting to increasingly frequent heatwaves, the unusual trend of travelers carrying cooling equipment across borders highlights growing concerns over climate extremes, while also serving as a reminder that aviation safety rules remain a key consideration for transporting household appliances.
In second quarter of 2026, China-Europe freight trains have transported more than 100,000 portable air conditioners and key components, with a total cargo value of about $52 million, helping to ease supply pressures in the European market, according to a report by China Railway Group media.
。宁波交通港航 供图　　在全球航运碳中和转型背景下，推进清洁能源替代传统船用燃料是航运产业升级的重要方向。绿色甲醇具有安全性能良好、船舶适配性强、低碳效益突出等优势。而宁波舟山港给远洋大船加注绿色甲醇燃料的历程，也就一年多。　　2025年9月29日，在宁波舟山港，7 辆专业甲醇运输槽罐车依次抵达码头，依托全套防爆加注橇装设备，给“中远海运天秤座”轮加注230吨甲醇燃料。　　今年4月22日，浙江省首单船对船绿色甲醇燃料加注业务落地宁波舟山港梅山港区。

D | 这次加注，采用改造船“大庆268”轮，同样是给“中远海运天秤座”轮加注，一共503吨，比此前的槽罐车模式快近6个小时。　　今年7月31日，专业化的“中燃绿能85”轮投运，陆续完成973吨普通甲醇和近5500吨绿色甲醇两批次大规模作业。这意味着，宁波舟山港甲醇燃料加注业务从示范试点迈入常态化、专业化运营新阶段，实现“三级跳”。

E | 　　据了解，“中燃绿能85”轮总投资超过1亿元，货舱用的是耐腐蚀双相不锈钢，既可沿海开展危化品运输，也可全天候开展船舶甲醇加注作业。　　今年8月16日，在上海港绿华山锚地，甲醇加注船“海港致远”轮一次性为大型甲醇双燃料集装箱船“达飞欧斯米姆”轮加注8016吨国产绿色甲醇，刷新全球绿色甲醇单次加注量最高纪录。　　不同于锚地作业模式，宁波舟山港8月23日实现了码头靠泊状态下的船对船加注。该作业需要统筹码头调度、船舶靠离、岸基保障、现场安保等多项工作，挑战较大。加注成功也意味着，宁波舟山港具备承接大规模甲醇燃料加注需求的完整能力。　　宁波交通港航部门披露，当地将推广全链条服务模式，联动口岸、码头、航运企业，拓宽绿色燃料应用场景，吸引越来越多绿色环保船舶靠泊宁波舟山港加注绿色甲醇燃料。
