Popins, I never said that you personally did not know how to swim, and I understand that you were told aparently by the recruiter that you could 'just say you did' (know how to swim) on the form (which unfortunately if you dont know how to swim is still a lie?). But the bottom line is, if you are required to know how to swim, dont you think it is better to be skilled in this area, since it is obviously there as a requirement for a reason?
I am very suprised that you knew Flight Attendants that managed to make it throught the training without swimming skills (this is not a reflection on you) because they are putting themselves and others (that trust the skills of the Flight Attendant) in a compromising situation, its just not safe.
