I own a travel agency, that is a "franchise" of sorts with a much larger group - and we have native access to Sabre. Sabre GDS and Sabre SONIC are 2 different systems (albeit same ownership and 95% same commands, its a hard "wall' between the two) - and thankfully our Sabre shows its an NDC link to AA, so I'm not sure how this is really going to affect corporate travel.
