Why Are Some Airplanes Crowded During the Health Crisis?
Every once in a while, pictures or videos of airplanes nearly full of passengers appear on social media. That seems to violate advice from public health officials related to social distancing during the coronavirus crisis.
Some people have raised the question: How can airplanes still be full when air travel has decreased more than 90 percent from a year ago?
In some cases, airlines are creating the crowds. They are canceling flights. Passengers must then crowd onto the few remaining planes.
The airlines, however, say that they are taking action to ease passengers' fears about coronavirus contagion. Some are blocking middle seats — or letting passengers pay extra to guarantee an empty seat next to them. They are also starting to require passengers to wear facial coverings.
People are still flying
The number of people traveling on airplanes is at its lowest level in many years. There are only about 17 passengers on the average flight within the United States. But that is an average.
The number of people passing through airport security has been rising since the middle of April, but it is still down 93 percent from one year ago.
So, why are some flights full?
Partly, it is because of the high number of canceled flights.
On routes where there used to be several flights offered by different airlines, now there may be two or three, said Robert Mann. He is a former airline official in the New York area.
Airlines have sharply cut their flight offerings. They also cancel flights in the few days before departure. That can force passengers who were scheduled to be on many different flights to be on the same one.
Some planes are more likely to be crowded, especially those between hub airports operated by the same airline.
Another question is whether airlines are spacing passengers out.
Several airlines are blocking some middle seats. Delta Air Lines, for example, said recently that it will block some window and aisle seats until June 30. This will leave 50 percent of first class and 60 percent of the main area empty. Southwest chief Gary Kelly said his airline will temporarily limit the number of seats it sells, probably to 67 percent.
Frontier Airlines said that, until August 31, it will guarantee passengers an empty aisle seat next to them — if they pay between $39 and $89.
Covering your face
What about face coverings?
All the leading U.S. airlines have announced plans to start requiring passengers to wear face coverings on flights. JetBlue Airways was the first to announce the policy, which took effect May 4. Recently, Delta, American, United and Southwest have also made it a requirement.
Airlines say they will not let passengers board a plane without masks. But, small children and people with some medical conditions will generally not have to wear them. Others will be permitted to briefly remove coverings while eating or drinking.
Flight crews are preparing for passengers who will ignore the rules.
An industry official told The Associated Press that airlines would not land planes if a person will not keep their face covering on "unless they are violent or crazy." The official asked not to be named since he was not permitted to discuss the airline's operations with reporters.
In addition, the airlines are requiring crew members to wear face coverings.
How do airlines clean planes?
Every airline says it has increased cleaning of plane cabins to help prevent spread of the coronavirus. Some, like Delta, say they are using special machines to spread anti-viral chemicals.
Airlines say that the air inside their planes is safe to breathe. Cabin air on most large planes is a mix of fresh air from the outside and air that is passed through high-efficiency air filters.
Changes will remain
And finally, how long will the changes last?
Until there is a proven treatment or widely available vaccine for COVID-19, the changes are likely to stay in place for a time. COVID-19 is the disease caused by the coronavirus.
If more people start taking airplanes this summer, it is still not expected to be anything like the summer of 2019.

There should be greater treatment of sewage before it is discharged.
We might try to clear up some of the cabins in the superstructure.

Our sanctions are basically banking and oil sanctions, and those sanctions will stay in place.
In the second Obama administration these are likely to stay in place or be extended.

每隔一段时间，社交媒体上经常会有人晒出飞机满是乘客的照片或视频 。这似乎违反了公共卫生部门有关冠状病毒危机期间保持社交距离的建议 。
其中一些情况是航空公司造成的 。他们取消了航班，导致乘客不得不搭乘仅剩的航班 。
但是航空公司表示，他们在采取行动缓解乘客对冠状病毒传染的担忧 。有些飞机封闭了中间座位或者让乘客支付额外费用买下旁边的座位，而且开始要求乘客佩戴口罩 。
搭乘飞机旅行的人数达到多年来的最低水平 。在美国境内，平均每个航班上只有约17名乘客，但这是一个平均值 。
纽约地区的前航空公司官员罗伯特·曼恩（Robert Mann）表示，过去由不同航空公司提供多次航班飞行的航线上，现在可能只剩下两三个在飞 。他曾是纽约地区的一名航空公司官员 。
航空公司已经大幅削减了航班数量 。他们还会在出发前几天临时取消航班，而这可能迫使原定要乘坐许多不同航班的乘客最终只能搭乘同一架飞机 。
一些航空公司封锁了部分中间座位 。例如，达美航空公司近期表示，它将封锁一些靠窗、过道座位直到6月30日 。此举导致头等舱的50%和飞机主要区域的60%闲置 。西南航空总裁加里·凯利表示，该航空公司将暂时限制其出售的座位数量，大概会限制在67% 。
美国所有主要的航空公司都宣布计划要求乘客在乘坐飞机期间佩戴口罩 。 捷蓝航空公司是第一个宣布该政策的公司，且该政策已于5月4日生效 。最近，达美航空，美国航空，美联航和西南航空也发布了这一规定 。
航空公司表示，没有佩戴口罩的乘客禁止登机 。但是，小孩和患有某些疾病的人可以不佩戴口罩 。其他人则仅在进食或饮水时可以暂时摘下口罩 。
一位业界官员告诉美联社，如果有人不戴口罩那么航空公司就不会让飞机落地，“除非他们暴力或疯狂抵抗” 。由于未获准与记者讨论航空公司的运营信息，该官员要求匿名 。
每家航空公司都表示，为防止冠状病毒传播，他们已经加大了对机舱的消杀力度 。达美航空等航空公司称，他们正在使用特殊的机器喷洒抗病毒化学物质 。
航空公司称，飞机内部的空气可以安全呼吸 。大多数大型飞机舱内的空气是外界新鲜空气与经过高效空气过滤器过滤的空气混合而成 。
在针对新冠肺炎的治疗得到证实或疫苗得到广泛使用之前，这些变化可能会持续一段时间 。新冠肺炎是冠状病毒引起的疾病 。
