I'm not sure if this is due to the rejigging of US fare codes but I would understand that if it was US inventory being affected but it seems like AA is being affected as well?

I've been looking at DUB-PHL, DUB-CLT, DUB-JFK, DUB-ORD for xDUB *O sale on. It was only a couple of days when it went from 6-7 i to 0 overnight on US. But now it looks like AA schedules are having issues as well. A couple days ago I saw schedules and inventory for AA flights up till early December and now I don't see anything departing either ORD/JFK to DUB past the 3rd week of October. Similar issue with CLT-DUB (unless its a seasonal service?).All this while PHL-DUB and vv remain absolutely fine.

Should I just assume this is all related to the fare code rejig?
