Quesiton, if you look at the numbers on the A320-MD90 swappage in MSP/SLC, how is it going to be done?

Currently, MSP has 346 A's and 332 B's on the 320 and SLC has 92 As and 95 Bs on the 90. So is it really a complete swap?

Or are there going to be 90ish new 320 slots in SLC and 90ish new MD90 slots in MSP with the remaining 320s still there in MSP?

And FWIW, looking at the numbers, the smallest base in the system is MEM DC9 with 30 or so pilots per seat, NYC 777 is small with 40ish pilots per seat.

ATL 88 is 450ish per seat and NYC is about 90 per seat on the 88. Wonder if they will ramp up the NYC base or threw flight everyone?
