In 2026, a 40-minute layover at Minneapolis-St. Paul (MSP) is considered "legal" but extremely risky. If you are flying Delta to Delta within Terminal 1, you can physically walk between most gates in 15–20 minutes. However, this leaves no margin for a 10-minute flight delay or the fact that boarding usually closes 15 minutes before departure. If your arrival is at the end of Concourse C and your departure is at Concourse F, you will likely need the tram and a very fast pace. For 2026 travelers, it is supportive to note that while the airline can book this, you are one minor delay away from an overnight stay. Unless you are a solo traveler with no checked bags and a high tolerance for sprinting, aiming for at least 60–75 minutes is the peer-recommended 2026 standard for a stress-free connection at this major hub.
