The first part is correct; when AA emails you an itinerary it does not have the price breakdown. The second part is not correct; the AA agent can see the detailed price breakdown, including the amount as "taxes" (which includes fuel surcharges). But some agents don't like digging in to get it and then reading it to you, so you may want to call back. To just learn the cost details, you don't technically need the RTW desk; a regular agent (e.g., EXP desk) can see the record and give you the info; if you explain that you only want information on the locator, not to make changes or ticket, a regular agent should be able to help.
