The AEP-IGR route is in an economy-only plane, so no J possible there. Hopefully, if that's the only one, you can include it on the same routing but just accept "downgrade" to Y on that leg. However, be aware of that in case it creates booking hickups.
I dunno about any of the other legs. Make sure enough of the itenerary has J seating to making using a J award worthwhile, unless booking with a J award makes it possible to get Y seats that you can't with a Y award (but I don't even know if that would be the case or not).
