Chase would be the TA. Does
DCL still automatically assign the current TA to the new placeholder? I haven't used a TA on a DCL cruise since our first (disaster) so it's easy for us but I've been trying to keep up on the policy changes.
If you have a TA on this cruise then book the placeholder and it's auto assigned to that TA, you'd have to ask that TA to transfer it to Chase to use UR on it.
Since we've been happy with getting discounted GC's to pay for it and are happy with the OBC the OBB gets us, I haven't been concerned with trying to use an agency. But I'm curious now that I have the Chase avenue open. I know you could name the TA before but I thought that stopped and they went to the auto-assign and if not it's Disney's and they give you the 30 days to transfer to a new TA. (at some point I have to get back to the DCL boards now that I'm armed with all this travel hacking info here
)
