I would not have thought this itinerary to be possible with 60,000 CO miles, but my sister booked it for May over the phone today:

ICT-DEN-EWR-MUC-TIA(5 day stopover)-MUC-BSL(14 day stopover)-MUC-YYZ-ORD-ICT

How was this calculated out at 60k miles? I can see the outbound ICT-TIA for 30k, but how does she get to Basel for a 14-day stopover, backtracking to Munich on the way back for no extra miles? I'd mainly like to know because there must be a trick here I'd like to use for myself in the future.
