First of all, it is an excessive practice to ask flight attendants to stop flying and lose weight immediately if they are overweight 10%. Flight attendants need a certain amount of physical strength and energy, but it doesn't mean that only light-weight people can be qualified for this job. Some people are overweight but healthy and fully qualified for this job. Therefore, it is unreasonable to judge only by weight and ignore other important factors.

Secondly, this practice may have a negative impact on the physical and mental health of flight attendants. Asking flight attendants to lose weight in a short time may lead them to adopt unhealthy methods to lose weight, such as dieting and excessive exercise, which is harmful to their health. In addition, this practice may cause stress and adverse effects on the psychology of flight attendants, affecting work efficiency and service quality.

Finally, this practice may cause public dissatisfaction and controversy. Some people think that this practice is discriminatory and unfair, because it only takes weight as the standard and ignores other factors. This may affect the reputation and image of airlines.

To sum up, it is unreasonable for HNA to ask flight attendants to stop flying and lose weight immediately if they are overweight 10%. We should evaluate the physical condition and working ability of flight attendants more scientifically and comprehensively, ensure the physical and mental health of flight attendants, improve service quality and respect the rights and opinions of the public.
