Assuming I can ticket the following (or any) AONE4 on-line/e-ticket (w/o a phone call), will I be sacrificing AAdvantage miles if the first segment is a carrier other than AA?
(I am AA EXP but this is my first RTW, after 23 years of dreaming of it.)

ICN-HKG-LAX-JFK-DFW-ANC-DFW-LHR-HEL-LHR-DBX-LHR-JNB-HKG/DEL-HKG/ICN.

Also, does it look like I should be on a CX flight w/ its new suites? If not, any suggestions for a change to the itinerary in order to get a CX suite?
