As for the new 2004 OP Program changes, it is clearly printed the CO chart that for
Fare Class Flown: J, C, A, D & Z-- the Base Mileage Earned is 150% and the Elite Mileage Earned is 150%
But perhaps that only pertains to CO tickets for OP members???
And as I've already booked 4 Z and 2 D fares overseas, I'll be expecting my 150%
