I was on ABC Worldnews last year for my travels to keep the miles. I flew:
MCO - MIA - ORD - IND - ORD - DFW - DEN in one day then four months later I flew:
IND - ORD - DFW - SFO - MIA stayed overnight in a Radisson (2000 AA Miles for the stay) then 7 hours later:
MIA - SFO - DFW - ORD - IND
Also 2 weeks later:
IND - DFW - SFO - ORD - ARN
All for the Platinum Run!
