"Pref-bidding would only work if we could create the pairings and had complete control of the parameters loaded into the pref-bidding software. "
I can hear the company laughing at this a mile away.
"This should be done at least 4 time to get the best pairing efficency. "
Never has this been a priority in Miramar.
"Pref-bidding will not work because they almost certainly would not let us have complete control of the program and marketing would not give the information to planning with enough time to optimize the pairings."
Words of wisdom and experience. NC are you listening?
"The last system they proposed in after the last contract was Navatechs, and the most recent was Karmen. The same program that NW uses."
What a strange coincidence. Want to bet bet that Miramar envisions a system exactly like what NWA uses? You will lose transition conflicts. You will lose training conflicts. You will lose vacation conflicts.
"Also, Spirit can not be trusted to run any computer program by itself"
The fox guarding the hen house.
