Flight
When heading back home, if you go to https://www.mspairport.com/airport/msp-reserve, you can tell them when you'll arrive to the airport. You can reserve a spot in the TSA line. Just show the agent the code you get. This way you can skip most of the security line (it can get long)
Flight
Cheap Minnesota airline that Dylan and I have used several times, highly recommend. Just be aware of bag fees.
