Last week, there was another "epidemic" in Shanghai. Because it is related to flights, Air China was once sent to a "hot search". However, Air China's public relations is very powerful, and half a day's kung fu news is gone. In fact, netizens did not say anything, although they suspect that Air China's elimination work is not in place, but they are all speculations, not evidence. Not to mention that Shanghai quickly controlled, let alone worry.

A friend asked whether Air China's "string flight" is true? The general inspection found that the Air China A330-200 aircraft, numbered B-6090, did arrive in Taiyuan from Warsaw on November 14, and the flight number was indeed CA738; the aircraft took off again at 09:42. At 14:26 p.m. on Nov. 15, it carried out flight CA1521 from Beijing to Shanghai – and in terms of flight information alone, the "rumors" were indeed accurate.
On the 25th, some of the three cases in Shanghai took CA1521 on the 15th, and she traveled to Suzhou with two friends. The Shanghai municipality reported that "the epidemic stemmed from the exposure of contaminated aircraft in other provinces and cities", which is basically equivalent to acknowledging that she is the source of this time. Some netizens thought that the time in Nanjing on July 30 was also brought by Air China CA910, so they resented Air China even more.

But this is completely unnecessary. At present, everyone is very vigilant, and It is impossible for Air China not to seriously eliminate the killing. The spread of CA910 in Nanjing was later officially described as "due to irregularities in the protection elution (of the cleaners), which may have caused infections among individual cleaning personnel", so Air China was not responsible.
At this time the year before, some experts said that the coronavirus could only live about 6 hours away from the human body, so according to the theory of "experts", even if B-6090 did not do elimination, it was not dangerous to fly to Shanghai the next day - fortunately, it was supposed to fly to Guangzhou on the afternoon of the 14th, but the CA1379 on that day was canceled.
In short, complaining is not positive, and it is even more undesirable to blame each other. Everyone should do a good job of protection in order to do a good job in epidemic prevention. As for why Air China "flew in a string"? Why not separate domestic and international flights, La Zong also explained here.

Unlike cars, the "lifespan" management of an airplane is slightly more complex. In addition to engine life, the fuselage also has two indicators: "flight hours" and "take-off and landing cycle". Which of these two arrives first, the aircraft must be "retired" and cannot continue to be used.
Airplanes have more indicators of "take-off and landing cycles" than cars, mainly because of pressurization. Modern aircraft "blow balloons" after each takeoff, and the fuselage has to bear a lot of pressure. After the number of take-offs and landings exceeds the design standard, it is easy for the body to fatigue and cause air disasters. In 1988, Aloha Airlines had a Boeing 737-200 aircraft cabin torn during flight in Hawaii, which was caused by the short distance of the total flight, the large number of take-off and landing cycles, and the fatigue of the airframe.

In order to make full use of it, all airlines will now evenly arrange the "combination of length and shortness" of aircraft, that is, to pursue the balance of "take-off and landing times" and "flight hours". Aircraft have a tendency to design, such as short-haul aircraft will consider more about the solidity of the fuselage and landing gear, and Boeing has also launched a "reinforced" 747 aircraft specifically for Japan.
But in general, this matter is still done by the airline through "scheduling". This arrangement is "long-term", as long as it is balanced over "a period of time". Some companies frequently arrange short routes in the early stage of decommissioning, which is also possible. It's not just Air China that's doing it, it's the airlines that do it.
The A330-200 is a long-range aircraft. It doesn't carry a lot of passengers, but it can fly very far. During the epidemic period, there is very little international passenger flow, so It is actually understandable that Air China arranged for it to "fly in a string" in China. Air China actually less places A330-200 on the Beijing-Shanghai route, which has a large passenger flow, and Air China uses more A330-300 and 777-300ER. It may be affected by the "acid into Beijing" policy, but also had to arrange the A330-200 at the golden moment.

It would be inappropriate to accuse Air China of not seriously killing, and it would be even more irrational to carry out a regional attack. But Air China is China's third-largest airline, with more than 200 aircraft at its headquarters in Beijing alone. Therefore, if we must separate the aircraft used in international and domestic flights, it is not difficult to do so.
