If there ever was a time not to fly disputed pairings, it is NOW.
The SIG is asking for our help and the optimizer has been tweaked into overdrive. If you want another twist of the knob pick up a few of these disputed pairings. The MD-11 bidpack was the worst I've seen in the 5 1/2 years I've been on the aircraft. This month was also the worst the SIG has seen as stated in the first sentence of the December SIG notes...."This has been the most dynamic and challenging build in the last six years."
