I have one route YYZ-IAH-MSY, and the IAH-MSY United flight is almost always miscalculated for SQD and a discrepancy email has to be sent. It doesn’t even calculate properly to the cowtool, nor proportionately make sense according to great circle miles.
Can you elaborate on that? I've had many adjustments made to A/SQD since it was introduced, and when it has been corrected, it has always been in line with great circle distance. The calculator should be accurate within a few cents. And that includes the many mixed AC/UA itineraries that I purchased from both AC and UA.
