Air Force One was a frequent visitor to PBI during John F. Kennedy's presidency in the early 1960s. Local voters defeated a proposal to relocate the airport around this time, instead choosing to expand the existing facilities. In October 1966 an eight-gate Main Terminal opened on the northeast side of the airport; in 1974 Delta Air Lines moved into its own six-gate terminal with the airport's first jetways. The Federal Aviation Administration (FAA) built a new Air Traffic Control Tower on the south side of the airport in this period.
