Ah a good interesting question
I agree with cheetah, in plain English it is 'old school' here. Personally, would I put that I was a cabin attendant while looking for a job in Maun? No. That is my personal opinion though.
In other words, it will not be of any advantage to you and there may be a doisadvantage. In my opinion, there will be a perception here that cabin crew is for 'pansies' or some crap like that, and Maun is a small place. It WILL get around and quickly!
Ive never heard of anybody whose been cabin crew so this is a guess. I do not work in Maun though so wait for a reply from lilflyboy, Im working on my perception of Botswana as a whole.
