Please bear with me as I explain the situation and then ask my questions.

We booked flights from FLL-ORD-FCO and then FCO-ORD-FLL back home, back in July 2018 when bookings opened. We paid (didn't use points) for Premium Economy for the ORD-FCO and FCO-ORD legs. It's a 788 Dreamliner plane doing those routes on that day. We even snagged the bulkhead with the real footrest.

Flight is coming up in June 2019. I logged in to aa.com this morning to see that my flights home are completely different. They now have me headed out FCO-CLT in ROW 40 of regular economy of a 333 (yeah, the row by the bathroom and can't recline, that one).
After some digging I found out my FCO-ORD route is still there, but my flight from ORD-FLL is not. There are no flights from ORD-FLL after our FCO-ORD flight lands. So I completely understand why I can't have this route anymore. I'm not upset about that.
There are other flight options with PE but they leave FCO early in the morning and the earliest we can get to the airport is 11am to head home from FCO.

I called to see what can be done. We bought PE on purpose for the transatlantic legs of the trip. I was told I have two options:
1) Cancel the entire trip and rebook. No thanks, I don't want to lose my outbound flights in the seats I currently have. I also don't want to pay double since prices are almost double at this point.
2) Wait. They may add another route after Daylight Savings Time begins. If I don't accept the change, they can move me back to PE if a new flight is added from ORD-FLL making my original booking doable again.

Now, for my questions-
Is this DST an actual thing with AA? I have never heard of that in my life. She said that after daylight savings time they might add more flights. I work in the travel industry, I just don't deal with air much so this is new territory. But that just sounds like a completely odd way to determine if they need more flights?

Waiting. If I wait for a ORD-FLL flight to come available and then AA moves me back to my original FCO-ORD flight, I probably won't be entitled to the seats I had originally, will I? My guess is someone will scoop those up rather quickly and they aren't going to bump someone even though I had them from July to February?

Am I entitled to a partial refund should PE not become available? The lady at AA told me no, but I find that hard to believe.

I asked the phone agent if they could at least move my seats so I am not in Row 40 with non reclining seats. She told me that the only available seats left are Preferred and cost more money and I'd have pay that difference as I am not entitled to those seats with my current reservation. Okay fine, but then she added that If I make any changes that means I "accept" the change AA made and I am no longer eligible for them to move me back to PE should a new flight come available. So I have to just stick with Row 40 even though I paid for PE. Is this accurate or did I get someone on the line that's just giving me a hard time?


I totally understand the limitations of my situation but find the AA response to be very disappointing and illogical. Move a PE passenger to the worst seats on the plane? I would imagine that a sound policy would make me eligible for at least MCE or a Preferred Seat for this type of change. When I originally booked, I was granted MCE for my domestic legs because of the PE transatlantic portion. I read through the website and couldn't really find the policy that pertains to my situation.

I am very flustered and I am unsure of what to do and what is actual policy. I appreciate any advice from someone who may have some insight.
