2) Medium company outsources medium travel spend to CWT, Amex etc, with direct GDS access, payment by corporate credit card typically. Maybe has some deals with BA and different deals with other oneworld airlines.
3) Small company books travel on corporate credit card but it's in the name of the traveller, and is booked via BA.com
4) Very small company gets traveller to book themselves and claim back.

You won't get POUGs on 1 or 2, perhaps 3 too. You can't have an AUP on 1. You may be able to UUA 2, 3, 4. Now 4 and perhaps 3 is effectively the best option in this area since (e.g. you can call within 24 hours of booking and upgrade to WTP for just the fare difference and no change fee).

Essentially it's all about ticket ownership, Know Your Customer, and whether the fares are public/published or not. Option 4 is the only one guaranteed to have ticket ownership with BA, known BAEC customer and published fares. A BT/IT ticket is at the other extreme - perhaps ticketed on AA, perhaps a BT/IT fare, not published, payment detached from the traveller.

And as I say there are dozens of variants in between.
