History - Inter-war period

In year 1922 the bomb damaged aerodrome was reconstructed by Aviation division of the Republic of Latvia led by Jāzeps Baško. Soon after that the civil airport was set up on the 51 hectare land near Riga - Bolderāja railway branch and the highway; Riga city leased the airport out to the Latvian Post and Telegraph Department. The airport facilitated the hangars of Latvian Ministry of War, hangars of Latvian Guard and civilian aviation hangar hangars for Riga-Liepaja line aircraft and private aircraft parking. In year 1938 a new terminal building with passenger waiting rooms and restaurants, post, customs, police, militia and meteorological station was built by the architect David Zarins’ project. A “Telefunken" goniometric station was installed to determine the geographical position of aircraft in air. In 1930 the Ministry of Transport Division of the Air Trafic began to register the Latvian civil aircraft and gave the call-sign YL.
1928. gadā Spilves lidostu iekļāva Vācijas–PSRS gaisa satiksmes sabiedrības "Deruluft" tīklā un līdz ar to šeit nosēdās lidmašīnas, kas uzturēja gaisa satiksmi no Berlīnes uz Maskavu (līdz 1931. gadam), Tallinu un Ļeņingradu (līdz 1936. gadam). Pēc "Deruluft" likvidācijas 1936. gadā Berlīnes - Rīgas - Tallinas - Helsinku gaisa satiksmes līniju pārņēma Vācijas valsts aviokompānija "Lufthansa", kas izmantoja 18-vietīgas lidmašīnas. 1932. gada 17. augustā Polijas aviokompānija "LOT" ar 8-vietīgām lidmašīnām atklāja lidojumus transkontinentālajā gaisa satiksmes līnijā Helsinki – Tallina – Rīga – Viļņa - Varšava – Ļvova - Bukareste – Sofija - Saloniki - Atēnas, ar pagarinājumu līdz Palestīnai. Lidojumi notika trīs reizes nedēļā. Zviedru aviosabiedrība "Aerotransport" (vēlāk "A.B.A.") ar 12-vietīgām lidmašīnām un padomju "Aeroflot" ar 10-vietīgām, 16-vietīgām un 20-vietīgām lidmašīnām no 1937. gada 1. jūnija veica lidojumus maršrutā Stokholma–Rīga–Maskava. 1937. gada 15. jūnijā atklāja gaisa satiksmes līniju Rīga - Liepāja, kuru apkalpoja pirmā latviešu aviosabiedrība "Valsts gaisa satiksme" ar divām 7-vietīgām lidmašīnām. Sākot no 1938. gada gaisa satiksme notika visu gadu. Līdz 1939. gadam ticis plānots atklāt gaisa satiksmes līnijas Rīga - Ventspils - Liepāja un Rīga - Krustpils - Daugavpils, kas tomēr netika realizēta. Spilves lidosta strauji attīstījās - ja 1936. gadā tika reģistrēti caurmērā 40 - 50 pasažieru dienā, tad 1938. gadā jau 100 pasažieru dienā (ieskaitot tranzīta pasažierus).
In 1928 Spilve Airport was included in the German-Soviet air company "Deruluft" network and thus the planes performing flights on Berlin-Moscow (until 1931), Berlin-Tallinn and Berlin-Leningrad lines landed here. After the "Deruluft" liquidation in 1936 the Berlin - Riga - Tallinn - Helsinki route was taken over by German airline Lufthansa, which used 18-seat aircraft. On August 17, 1932 the LOT Polish airlines launched flights on the transcontinental route Helsinki - Tallinn - Riga - Vilnius - Warsaw - Lviv - Bucharest - Sofia - Thessaloniki - Athens, with extension to Palestine flying eight-seat planes. Flights were performed three times a week. From June 1, 1937 a Swedish airline “Aerotransport” (later "A.B.A.") with 12-seat planes and Soviet “Aeroflot” with 10-seat, 16-seat and 20-seat planes flew the Stockholm-Riga-Moscow route. In June 15, 1937 the route Riga - Liepaja opened which was served by the first Latvian airline “National Air Traffic” with two 7-seat planes. Starting from the 1938 the air traffic was maintained throughout the year. There was a plan to open Riga - Ventspils - Liepāja and Riga - Krustpils - Daugavpils routes by year 1939, however this did not materialize. Spilve Airport developed rapidly - if in 1936 there were on average 40 to 50 passengers per day, then in 1938 there were already 100 passengers per day (including transit passengers).
