We agree that the 500 mile attribution for short-hauls is an exception in the client's favour. That being said, I'm more than happy to take the "free" 355 Q miles I get on YQB-YUL.

I also agree with you that except in those cases, I have never seen a segment where the pax earns more miles than what appears in the timetable. I have not studied the entire timetable to confirm that though ....

However, I think that most of the differentials between timetable and posted miles are less than 20 miles per segment, perhaps less.....why does this discrepancy exist ? I don't know. Some here have pointed out possible "technical" reasons for such variations.

Could the timetable be published with the actual credited miles ? Sure, probably.

Is it a big deal ? No.

Is it fraud ? No.

Those of us who aim to hit status thresholds know the actual miles given for the segments that we fly and we plan accordingly. <shrug>
