BA don't require A levels for DEP's and E-Fizz's qualifications are just fine. What won't count though is the wealth of life experience as despite your enthusiasm for life's achievements, it counts for little with the airline, particularly the likely first job you'll get.
At 34, you're too old for BA's cadet scheme, and they haven't recruited DEP's of that age with no line experience for as long as I remember.
I would have emailed you a load more useful information, but you don't have an email addy in your profile.
