Sorry if this has been answered already somewhere else, but I cannot find the answer.

If I same day change to a flight that is a longer routing, do I earn original ticketed EQM or actual BIS EQM? As an example, traveling DEN to SJO thru IAH is 2428 EQM, but if all the stars align, and I could possibly SDC to a DEN to SJO thru EWR for a BIS of 3831 EQM what would my OnePass account be credited. Would it also work in reverse, netting less EQM??
