Could you please explain your question a bit more? Is this a class assignment or a job application section? If so what background information do you have?
Once I hear back from you I will send you my 4000 character answer.
If you could please tell me a few reasons you would like to work in cabin crew as well as any experience you have in the area I will write you an answer.
I have taken what you wrote and rearranged some things and added others. I know you had 4000 characters to use but you are better off to use less characters and write a compact answer which takes less time for the employer to read. I think in the answer below you show your desire to work for BA. If you have any experience working with a cabin crew you can add that to your answer.
