Keep 2hrs due to Thanksgiving holidays
Allow 90-120 minutes.
2 hours ahead is safe and stress-free.
Usually an hour and a half should be enough time if you know your way around the airport
2 hours before your flight time is a good time to arrive at Mitchell. I would bring a snack and water bottle as almost all the shops will be closing when you arrive.
2 Hours is a good rule of thumb, but usually not a long security line at MKE. You may also want to check with Frontier. Safe Travels.
