Delta G concourse has lots of power, food and drinks ordered via iPads. Just make sure you fully delete items out of your cart if you don't want them....
Lots of food,bars, and shops in this airport. This is very convenient since flights rarely leave here on time. At least you'll have stuff to pass the time.
No smoking lounges in the airport but it's super easy to go out thru ticketing then right back in thru security, just make sure you have your boarding pass and ID
If you don't have any checked bags and are renting a car use the skyway checkpoint. When leaving just make sure you have your boarding pass and check in the Skyway security. It us usually way faster
Never been in Minnesota before but nice airport (although bring ur walking shoes for connecting flights). French meadowbakery was a nice surprise amidst all the standard fast food chains.
Some of the best restaurants in the cities are in the airport. I recommend Ike's- they aren't capable of making bad food. Use the skyway checkpoint if you have no bags. Otherwise, gate 6 is fast.
MSP used to have easiest, quickest security process of any major US airport (and I fly hundreds of thousands of miles a year so have a reference point). As of February 2016, it's a complete cluster.
If you have time, head to the Observation Deck at terminal D. It gives you a great view of planes taking off and landing, plus a nice view of downtown!
Rental car goers beware! If landing around 11pm the rental car facility will most likely be closed by the time you get your bags (6am-11pm). no express pickups for any of the members programs either.
The Starbucks' here do not sell their cans of double-shot...bummer...the gift shops don't either! The glass bottlefrappuccinos are a close second for cold liquid caffeine.
Get to the airport early for the security check. They have reduced the number of scanners due to the new full body scanners. There is only one scanner per checkpoint now.
If your flight is departing from the G Concourse, get there early. Now that every gate has been turned into a restaurant/shop there's very few places to sit.
