Hi

I am planning a trip on CX Premium economy from SFO-HKG-BKK-HKG-SFO to put me over the top for EXP. I am trying to get the exact base miles that AA will use to calculate EQM and EQD's for this routing. I checked GCMap.com and compared it against my past activity on AA.com and there seems to be a few miles discrepancy between the two, so not sure what base mile reference AA uses.

As it stands, if I use GCMap.com to calculate base miles, I qualify with just 35 miles over the 100k limit. I want to double check before I book the trip and add additional segments if needed, so I don't end up short on the qualification with just a few miles left.

Can anyone point me to the source of truth for base miles that AA uses?

Thanks!
