I'm a below average swimmer, and got in with 2 airlines and passed the wet drills. I have a big fear of deep water and i feel sick at the though of gettin in the pool but i did it. However i did fail 1 airline becuase of this. I have been offered a job with BA but have told them that i cant relocate to london due to personal issues and they have told me i can get back to them within 3 months and my job offer will still be valid. This will give me enough time to learn to swim confidently.
