IIRC, he has said as much publicly. But replacing 40 900's might be tough...as much as everyone wants to cut capacity, mainline LOVES 900's (mainline capacity, regional cost structure). I think the delivery slots are all accounted for a ways out so in order to replace the MAG birds, DP would have to do a deal with another regional several years in advance to allow them to obtain delivery slots. Or airways could buy the 900's themselves now and farm them out later...not sure they have the credit rating for that though.
