Hey guys thanks for the information. I did understand about fare class (the first "L") but was unsure about alll the other letters after it. I think that tcook052 and DutchSE got the jist of what I was asking for. Sorry for getting people confused and heated.
I do understand of the different fare codes in existance and did check the Booking Class thread above but I believed that it did not seem to answer my specific question and wasn't sure of the remaining letters that might not let me accrue "Q" miles. I just wanted to make sure as the fare was the cheapest I have seen for a while (I ended up paying CAD$ 633.75 return which included taxes, fees etc. - not a bad fare I thought) and able to accumulate "Q" miles
