I am flying into MSP tonight and I will report what I can see. As far as I know there were no 727's with the new paint scheme. Their website did not have any info either.
They have been running a lot of charter flight to LasVegas recently including flights from Brainerd, MN and Grand Forks, ND.
Neither of these 727's were the new colors.
Remember when sex was safe and flying was dangerous?
