Think it depends on the airline and whether they allow agent bookings. Last I knew, BA.com created them on 1A but that may have changed with NDC.

For web they create them on 1A, but directly in 1A PSS, not going through 1A GDS (and therefore not paying the GDS fee, just a PSS fee). This is the case for all direct channels (websites or airline call centers) of all airlines
