Is the coffee and tea on the plane clean? Not to mention how much pollutants will be contaminated during the operation of the aircraft. The water tank on the aircraft will not be washed once for a long time. I won't describe how dirty it is. The service personnel on those planes will not drink the water from the plane. Moreover, the hot water on the plane will not boil, the highest is only 80 degrees.
Since items on the aircraft are reused indefinitely, they are often not effectively cleaned.
The seats on the plane are very dirty and do not touch them. I witnessed some people with reduced mobility defecation in their seats, then dried on the seat, and the seat cover that was basically not backed up was replaced. There are also some virus carriers who vomit directly on their seats and carpets (unintentional attacks and discrimination against patients, but just want to express the irresponsibility of these airlines at the airport). There are no specific management measures at the airport, they are put into use with a simple process.
It is best not to go to the plane to go to the toilet, the toilet is not very clean.
It is best not to use a blanket on the plane. The blanket is cleaned only once in a few days, mixed with various unknown liquids, saliva, etc. Some passengers will habitually cover their heads directly. Every time I saw it, I wanted to tell him how unsanitary it was.
