Several years later, namely in 1944, the place was renamed Weir Cook Municipal Airport to commemorate Harvey Weir Cook of Wilkinson, the US Army Air Forces Colonel, who died during the World War I, having won seven victories.
In 1962, the Indianapolis Airport Authority has got power over the airport. Since that time, it is responsible for the airport management and copes with the task pretty well. Fourteen years later, in 1976, the airport has got is current name to be known worldwide as the Indianapolis International Airport.
The airport expanded a lot since 1957 and up to these days. This especially concerns the major passenger terminal of the airport, which was initially located on one side of the airfield in the High School Road direction. Later, however, it was expanded thrice, namely in 1968, 1972 and 1987. Finally, the facility along with the International Arrivals Terminal, which was constructed in 1976, was renovated to become the Col. H. Weir Cook Terminal. This happened on November 12, 2008.
In 1944, another governing body, BAA, started managing the Indianapolis International Airport. They have got a 10-year contract to do that. After that, the contract was prolonged for three more years, but it was soon stopped on the demand of the BAA. Thus, the International Airport Authority regained control over the airport at the end of 2007.
Ten years later, in August 2017, the Allegiant Air adopted the decision to open a powerful aircraft base at the Indianapolis International Airport. It has to start working in February, 2018. Delta Air Lines, in its turn, declared their intention to introduce the new flight in the Indianapolis - Paris direction, which has to start on May, 2018.
