At Minneapolis-Saint Paul International Airport (MSP), Terminal 2 is the base of operations for Check-in and security Frontier Airlines MSP Terminal  processes move more quickly at this terminal, also called the Humphrey Terminal, because it is not as crowded as Terminal 1. The check-in counters for Frontier are situated close to the entrance, and security checkpoints are usually effective. There are a variety of food and retail options available once you pass security, however they are more constrained than in Terminal 1. Arriving at least two hours before your flight can make things go more smoothly, especially during busy travel periods.
