I thought this was an easy question but can't find a simple answer - I have an AA marketed/operated ticket (with 1 segment on American Eagle) coming up for PHL-DFW-ICT and reverse. I'm debating whether to credit to AA or QR. I'm trying to figure out how to use the Qpoints calculator for this as I get 2 different answers depending on whether I search a roundtrip PHL-ICT or I search 2 roundtrips - PHL-DFW and DFW-ICT. Can someone confirm which is correct? I thought it was the latter, but that will make or break which airline I credit to.
