If it is the latter, you should be able to avoid baggage fees (as long as you get the right GA).
Nothing so neat and tidy as one itinerary. These are 3 separate PNRs on mostly different airlines (with a sufficient layover between each one). The only reason I ask is, as I mentioned, the only other time I've flown AA post-baggage fee I was able to get out of the fee on PNR 1 by showing PNR 2, which was a continuing international flight on AA a few days later. Since I'll be coming from an international destination (on a OW carrier no less) I'm sure it won't hurt to ask, I just wanted to see what people thought my chances were.
