Northwest Runway in October 2011 the airport was predicted to be able to handle 126 movements per hour. It is predicted that aircraft movements will increase up to 700,000 in the year 2020. By using the fourth runway, Frankfurt Airport is able for the first time to handle simultaneous parallel landings, because the distance between the north and the north-west runways is . Simultaneous parallel landings were not possible with the north and south runway pairing, because the separation distance did not meet the safety standards. During normal operation the two outer parallel runways (07L/25R and 07R/25L) are used for landings and the central parallel runway (07C/25C) and the Runway West (18) for take-offs. The three parallel runways have two markings because they can be operated in two directions while the Runway West can only be used in one direction. Future expansions Terminal 3 (under construction) In 2009, the German government decided to create third terminals for both Frankfurt Airport and Munich Airport in order to handle expected passenger flows of 90 million in Frankfurt by 2020 and 50 million in Munich by 2017. The new terminal is scheduled to be built by Fraport, south of the existing terminals on the grounds of the former Rhein-Main Air Base. The new Terminal 3 is to accommodate up to 25 million passengers and will feature 75 new aircraft positions when completely constructed. An extension of the SkyLine people mover system is planned to connect the new terminal to Terminals 1 and 2 and the airport train stations. In August 2014, the city of Frankfurt granted building permission for the first phase of Terminal 3. The groundbreaking for the new terminal took place on 5 October 2015. Its first phase, consisting of the main building and two of the planned four piers (concourses 3H and 3J), is planned to open by 2026 and will be able to handle 15 million additional passengers per year. Total costs are estimated at 3 billion euros. In 2017, Frankfurt Airport first indicated that the second-phase construction of the easternmost pier (concourse 3G) could be moved forward so that low-cost carriers can use this pier from 2021. After approval by municipal authorities in 2018, the piers will be constructed and used according to the following timetable: Due to the COVID-19 pandemic, Fraport postponed the opening of the new terminal to 2026 in March 2021.
