No LCC competition on the route. There's not a whole ton of LCC competition at MSP - Sun Country flies to some leisure destinations, while AirTran has a handful of flights. Of course, neither AirTran or Sun Country fly to BDL, so you're stuck with legacy carriers or Midwest (who I've seen as the cheapest option quite a bit on BOS-MSP via MSP).

Really hoping that WN comes into the Humphrey Terminal sooner than later...
