But "A" daily 737 just doesn't work. The Paris route from Cardiff has traditionally been a business route, with the route paid for by the boys and girls in Club, or paying Y class tickets. So it has to be double daily. So that is 600 seats per day with a 737. Baby would want to fill at least 500 of those, and at a sensible yield that covers the nasty costs of CDG. That just won't happen any time soon from this part of the world, I am afraid.
What it needs is someone with a smaller aircraft that can offer a BA type service. Baby wisely aren't touching it with a mucky stick.
