I am in the process of organising a DONE4 for two people:

AMM-YUL-DFW-PHX-DFW-RAP-DFW-LAX-BNE-AKL-ZQN-SYD-BNE-KUL-HKG-CDG-AMM

This priced out with the online tool at approx $16,300 USD.

Unfortunately the online tool wouldn't book it for me (same error many here seem to have reported) so I had to ring up the AA RTW desk to book.

I've been keeping an eye on the progress of ticketing via aa.com, and today I noticed that a number had appeared in the pricing for it.

That price is: $11,000 USD.

Now, I know booking through AA is supposed to be cheaper, but this seems like too huge a difference just for that ?
