The municipal government promised to invest 600 million yuan to improve airport efficiency by 60% and reduce delays by at least 79%. In June, 2005, the Federal Aviation Administration promoted this plan, and participated in the reconstruction of the airport structure and the increase of terminal space. In the future, four runways will be added and three runways will be cancelled to form eight parallel runways similar to Dallas. This plan can basically reduce the flight restrictions in O'Hare, and will not be eclipsed by other airports in terms of the number of passengers in the future. In addition, even in the worst weather conditions in Chicago, flights can take off and land faster. After a long delay, the modernization plan has been completed and the first runway in the plan is expected to be completed in 2008-2009. The third and fifth terminals will be expanded, and the new East Terminal is expected to enter the airport from the east. However, about 2,800 residents had to be resettled due to land requisition. In the plan, the daily staffing of the airport will increase to more than 3,800 people, higher than the current 2,700 people, which will greatly improve the passenger flow efficiency. The voices against the expansion plan mainly come from the neighboring communities Bensonville and Elk Forest Village. Because the plan will lead to the relocation of some residents and shops. Bensonville and Elk Grove Village formed the O'Hare Suburban Committee to fight. As of today, the Committee has made limited progress, but refused to accept the temporary ban issued by the FAA on urban expansion plans, and the ban soon became invalid. The O'Hare Suburban Committee is also expected to plan to build Peotong, the third regional airport in the southern suburbs. They think this will solve the existing problems of O'Hare Airport, but no airline has applied to enter this envisaged airport.
1995 Chicago signed a Chicago/Gary aviation contract with Gary, Indiana, creating a Gary/Chicago international airport management system that transcends state boundaries. Although the scope is smaller than Peotone's planned airport, the number of take-off and landing planes and runway length are better than those of midway airport, and the traffic is more convenient. Chicago is happy to see Gary Airport thriving, but Illinois is not conducive to the construction of interstate airports. Mitch Daniels, the governor of Indiana, provided the foundation for the expansion of the runway, and the FAA also agreed that Gary would become the new Chicago airport. Because in addition to expanding O'Hare, FAA also thinks Gary's expansion is imperative. Chicago/Rochford International Airport (RFD) in Rochford, Illinois. Recently, I have been studying one of the ways to reduce the traffic flow in O'Hare. Rochford is located above the northwest highway in O'Hare, about half an hour's drive from Chicago. At present, there is no direct train from Lower Chicago or O'Hare to Rochford Airport, but the flight flow of this airport is increasing day by day. Larry Morey Xi, the current mayor of Rochford, has been promoting the construction of a high-speed railway connecting the two airports since he took office, so as to promote Rochford Airport to share the traffic in O'Hare.
Mitchell International Airport (MKE) in Milwaukee, Wisconsin continues to improve passenger utilization in Chicago and northern Illinois. There are 7 trains from Chicago to Mitchell Airport, and it takes about 75 minutes to get to Chicago.
