I have to recommend the AA RTW desk for a far in the future XONEX.
We booked DONE3 back in March 2024 for travel starting January 2025.
Fortunately, we booked it with AA RTW because I've already received a couple handfuls of changes/cancellations to the itinerary that required phone calls.
One of the changes was cancellation of the first flight from ORIGIN.
Lots of phone time. At least it's a dedicated desk.
