I just happened to check a trip I'm taking in January and found everything changed but I was not notified. Flights are on AA, booked with Alaska miles. I looked the reservation up on the AA website; the schedule change was not flagged but the new routing was there.

Original routing was early morning SEA-JFK (3 hr connection)-LHR in First/Business booked with Alaska miles.
New routing is SEA-ORD (red eye with a 60 min connection) ORD-EWR (10 hour layover and an airport change) then the original JFK-LHR flight.

Does AA arrange the EWR-JFK connection or am I on my own and out of pocket for this?

There don't seem to be any other options for award flights that day. Should I just wait and see if anything better opens up in the next few weeks and then call to quest a change based on the extreme schedule change?

I now see that it is flagged on the Alaska site (only visible when I actually open the booking). If I call about the change and they can't find a good alternative, am I tacitly accepting the change and losing the chance to change if something better comes up later?
