There you go again, confusing low cost with no frills. Take off those orange-tinted spectacles and I will spell this out for you one last time.
You work for a no-frills carrier, who happens to be low-cost ("lo-co") also. Duo was "lo-co" but with frills. The common element therefore is in the "low-cost" - meaning, low cost base, NOT that all seats are for sale for 1p.
You'll never get into BA with such a poor understanding of airline economics, no matter how hard you try!
