The history of the airport starts in 1917 when, after the bombing of Pescara by bombers of the k.u.k. Luftfahrtruppen, the aerial component of the Austro-Hungarian Army, along the Via Tiburtina Valeria road a military airfield is built by the Regio Esercito, which arrived on 26 October 1917 with two Farman 14. On 31 July 1918 the 302° Squadron is formed, equipped with biplanes Ansaldo SVA, among the best fighter-bombers of the time. From 1921, the airport has been named after Pasquale Liberi, an aviator friend of the famous poet Gabriele d'Annunzio. In 1927 the airport was extended to 50 hectares and modernized. In the 1930s, with the start of commercial aviation, the airline Società Aerea Mediterranea (SAM) started in 1933 a triweekly service from Pescara to Rome Urbe Airport, with an intermediate stop at the airfield of Piana di Bagno near L'Aquila. After WWII, the first airline to restart commercial service was Società anonima di navigazione aerea transadriatica (Transadriatica), which inaugurated the service Pescara-Roma-Urbe on 5 May 1947 using a Douglas DC-3. At the same time, Transadriatica started another interesting route: Venezia-Ancona-Pescara-Brindisi-Catania. Furthermore, the airline Avio Linee Italiane decided to start a route connecting North to South Italy for the first time: Milan-Pescara-Foggia-Bari-Brindisi. Itavia, constituted in 1958 to operate between secondary airports not served by Alitalia, opened its first route Pescara-Roma-Urbe on 15 July 1959 with a 8-seats de Havilland Dove. With the development of Itavia also the number of routes increased between the end of 1960s and beginning of 1970s, including Roma, Milano, Ancona, Crotone, Forlì, Lecce, Bergamo, Bologna, Treviso-Venezia, Catania and Palermo. In 1973, the English historian Bruce Barrymore Halpenny, then living in Abruzzo, organised a British Caledonian BAC 111 to take off from Genoa Airport to Pescara to test the feasibility of the approach and landing at Pescara of a large commercial aircraft. With the British Caledonian chief pilot being an ex-RAF pilot and Halpenny (also Ex-RAF) on board this maneuver was successfully accomplished, opening up the airport and the region for tourism. Halpenny then arranged for a British Caledonian BAC 111 to take off from Gatwick Airport, land in Pescara and return to Gatwick, demonstrating the feasibility of commercial flights to the airport. As of 1 February 1979, Itavia was forced to suspend its flights to Pescara due to the revision of the minimum landing requirements on some Italian airports implemented by ANPAC, the National Association of Civil Aviation Pilots. The raise of the requirements in question (distance to the runway and altitude at which the pilot must decide whether to continue the landing) were dependent on proper radio support (such as ILS, Instrument Landing System) and a clear view to allow the landing of aircraft in conditions of poor visibility. Such instruments were not installed at the time at the airport. Itavia itself was never going to be back at the airport, as it ceased operations in June 1980, after the Ustica disaster. After the dark period during which the airport did not have any connection, the situation improved with the reopening of a route to Milano through Ancona, operated by Aermediterranea, a company belonging to Istituto per la Ricostruzione Industriale (IRI) and controlled by Alitalia, which was operated between 1981 and 1983. From 1984, the flight to Milan Linate Airport was managed by another company of the Alitalia group: Aero Trasporti Italiani (ATI), based in Naples. In 1988, it was the turn of Alitalia itself to operate the much-sought direct connection to Milan, using the modern McDonnell Douglas MD-80 jetliners until 1994. Air One was founded as Aliadriatica in 1983 as a flight school and air taxi company for services in Abruzzo. From 1994, it was this company who took operation of the route to Milan.
