Northwest owns 55 of the 70 gates. Plus 10 under construction. And fly 80% of all passengers out of MSP. I'm not sure how many flights there are a day at MSP but at their site www.mspairport.com it should show you.
MSP has more than 1,345 Flights a day. Thats just for Northwest. What about the other airlines? Also where are they adding 10 new gates to? I know they are working on the Humphrey Terminal. Thanks
