. According to the FAA, most airports are encouraged to have a runway safety area no shorter than , though many airports do not. Construction of the runway safety areas began at the end of summer 2009 and was completed in fall 2012. There was also a "Master Plan" idea to increase the terminal area by stretching the existing terminal (in some cases, to almost double the size) or begin construction of a separate terminal. Nearly all cases would involve major reconstruction on the airport itself, and would have a huge impact on the airport's traffic. These plans were, however, drafted before Mitchell saw a significant reduction in carriers and flights. More recently, in 2012, there were discussions of closing one concourse as a cost-cutting move. The approved 2018 Milwaukee County Budget contained initial funding for replacement of the now-closed Concourse E with a new International Terminal. It would replace the current International Arrivals Terminal (IAT) which has limited capacity and is not connected to the main terminal building. The new terminal was planned to open in 2020 after the demolition of Concourse E was completed. During October 2018, airport and Milwaukee County officials set a timeline for design, construction and completion of the new International terminal. Pre-design work and bidding concluded in November 2018, with construction set to begin in early 2021 and likely concluding in mid-2022. In May 2020, Milwaukee County announced with the

As of May 2025, the airport was seeking bids to demolish the existing concourse and build the new international concourse.

This would allow the airport to remodel the concourse and move International Arrivals processing into the terminal. Following redevelopment of Concourse E, the current International Arrivals Building just north of the main terminals will close. Airport officials are hoping to begin work in 2025, with the redeveloped concourse designed to have between 2-5 gates per the airport's Implementation Plan.
