You only see a 125 number for purchases from BA, they cannot plate in another airline, and that appears to be there. The interfaces to SABRE means you are perhaps looking at a lost segment detached from the main Amadeus booking, which is annoying from an App point of view but signifies very little. I would leave it until a couple of weeks before travel, see what it looks like at that point and if in doubt give the GGL team a call. It's a function of the complexities of your ticket, and I wouldn't be unduly concerned, an agent may think you are over-thinking it, but unless a couple of weeks from travel I doubt it's an issue at this point. Plus AA will probably change everything on Sunday anyway.
