MSP is our last choice but if it's the only way back, we'll take it. When we're up north for the summer (we'll be heading to New Orleans a week after we get back) JFK is primary and BOS is secondary. DTW's OK since we'll spend a day with our son and his wife and ATL gives us lots of options back to JFK (where our car is parked). When we're in MSY, DTW becomes primary with JFK secondary. We try to avoid ATL since there's so much nonrev in and out.
