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.
