"FLIGHTS WITHIN CANADA AND TO THE USA (EXCEPT HAWAII):
BC: J,C - 125% / 100% / 500
EC: Y,M,U,A,B,H,V,Q,L - 100% / 100% / 500
EC: R,N,G,P,E,T - 50% / 0% / 250 (aka, TANGO fares)"
This is correct for crediting AC flights to AC's Aeroplan program but not for UA (according to UA's website) which states.
"Economy Class worldwide—100% of actual, paid miles, or 500 miles minimum, on flights scheduled on Air Canada or Air Canada Connector® (within Canada, Full-Fare Economy)
Business Class worldwide—125% of actual, paid miles
Discounted flights within Canada—50% of actual, paid miles (or 250 miles minimum) "
In addition, it seems there is NO credit for TANGO fares. Based on various ff'ers difficulty getting points posted, UA's website seems to be quite poor in showing fares that are NOT eligible for accumulation in a number of airlines.
