THANK YOU ALL!!
not familiar, but I imagine Chicago paris on aeroplan would be united, which aeroplan doesn't charge YQ
Chicago-Paris on Aeroplan via US Air or Lufthansa, YQ over $500/ticket!
Chicago-Paris on Aeroplan via United (solo or with Lufthansa), no YQ! Crazy game.
Both are 60K miles R/T... I'm thinking about using American outbound, so I can add the free domestic leg and because their itineraries include an overnight stopover in London! Maybe Aeroplan for the return (United direct CDG-ORD, no YQ, 40K miles, though)?
I called to verify lap baby charges: Lap babies are $50 (Canadian, eh) or 5000 miles in economy (you can choose which you want). $100 or 10,000 in Business. EDIT TO ADD: Lap baby charge is per itinerary, not per leg.
