Hey!
I know there is HUCA and all...

Before I call back I'd like some of your insight.

I booked a DONE3 back in February ex-Cairo. Start is not until January 2025.

Yesterday, I received schedule change for the START DATE of the ticket that is for the same carrier but on the previous day. Not quite 24 hours earlier than originally booked.
Original RJ CAI-BKK via AMM.

I called AA RTW desk yesterday and rebooked QR CAI-BKK via DOH arriving BKK on the same day.

At the same time, because the agent said I could without charges, I moved the dummy dates for the remaining 14 segment to something more likely throughout next spring.

Overnight I got an email saying they could not proceed with the requested changes until they spoke with me.

I just got off the phone and after a bit told the nice lady on the phone that I'd have to HUCA.

She said that the new ticket incurs a $6k+ change in fees (not sure if it is per person). She suggested that I cancel the ticket and start over because regardless if I make the date changes now or after departure it will incur the same $6k changes in fees because they have increased since I booked.

I asked that the ticket be returned to original booking and she says it won't matter, price wise.

Advice?
