for TSA and customs inspections and much larger landside amenities such as shopping and restaurants. A principal feature of the plan is the reorganization of the terminal core into an "alliance hub," the first in North America; airside connections and layout will be optimized around airline alliances. This will be made possible by the construction of the O'Hare Global Terminal (OGT) where Terminal2 currently stands. The OGT and two new satellite concourses will allow for expansion for both American's and United's international operations as well as easy interchange with their respective Oneworld (American) and Star Alliance (United) partner carriers, eliminating the need to transfer to Terminal 5. This project will add over to the airport's terminals, add a new customs processing center in the OGT, reconstruct gates and concourses (new concourses will be a minimum of wide), increase the gate count from 185 to 235, and provide 25% more ramp space at every gate throughout the airport to accommodate larger aircraft. After an international design competition that featured public voting on five final architectural proposals, the Studio ORD group, led by architect Jeanne Gang (in collaboration with SCB, Corgan, Milhouse, and STL Architect,) was selected to design the OGT, while Skidmore, Owings & Merrill LLP will design Satellites1 and2. By terms of the agreement, total costs of $8.5 billion for the project are to be borne by bonds issued by the city, which will be retired by airport usage fees paid by the airlines. O'Hare 21 is scheduled for completion of the two satellite terminals in 2027 and 2028, and overall completion in 2030. Facilities Terminals O'Hare has four numbered passenger terminals with nine lettered concourses and a total of 213 gates. Terminal 1 is used for United Airlines flights, as well as international departures by Lufthansa and All Nippon Airways. It contains 52 gates on two concourses, lettered B–C. Terminal 2 is used for United Express, Air Canada, Alaska Airlines, and JetBlue flights. It contains 41 gates on two concourses, lettered E–F. Terminal 3 is used for American Airlines, American Eagle, and Spirit Airlines flights, as well as international departures by Iberia and Japan Airlines. It contains 80 gates on four concourses, lettered G, H, K, and L. Terminal 5 is the airport's international terminal. It contains 40 gates on one concourse, lettered M. All non pre–cleared international flights deplane here as it currently contains the airport's sole U.S.
