• April 13 - The first scheduled air freight service begins in the United States.
• April 15 - Ukvozdukhput/Ukrainian Airways begins services in Ukraine.
• April 21 – Italian aviator Francesco de Pinedo and his mechanic Ernesto Campanelli depart Rome on a 201-day flight in the SIAI S.16ter flying boat Gennariello that will take them to Australia and Japan before they return to Rome in November.

May

• May 1 - The Imperial Japanese Army Air Corps is established under the command of Lieutenant General Kinichi Yasumitsu. It has 3,700 personnel and about 500 aircraft.
• May 4 – Italian legislation sets the peacetime strength of the Regia Aeronautica (Italian Royal Air Force) at 182 squadrons, with 78 of them assigned directly to the air force, 69 to the Italian Royal Army, and 35 to the Regia Marina (Italian Royal Navy). The army and navy are given temporary command of the squadrons assigned to them for the length of time it takes to train them for wartime operations.

June

• June 10 – Italian aviator Francesco de Pinedo and his mechanic, Ernesto Campanelli, arrive at Melbourne, Australia, after a 50-day flight from Rome in the SIAI S.16ter flying boat Gennariello during which they have made 27 intermediate stops without serious mishaps.

The day-and-night flying allows the transcontinental air mail service to deliver mail notably faster than train-only service for the first time.

They had left Rome 86 days earlier and made 28 intermediate stops before arriving in Sydney. They will remain in Sydney for 21 days before continuing their journey through Australia and to Japan.

• August 7–9 – Flying in France on the route Chartres–Étampes–Toussus-le-Noble–Chartres, the French aviators Jules Landry and Maurice Drouhin set a closed-circuit distance record of 4,400 km in 45 hours 11 minutes 59 seconds in a Farman F.62.
• August 31 – Two United States Navy Naval Aircraft Factory PN-9 flying boats take off from San Francisco, California, in an attempt to make the first transpacific flight from North America to the Hawaiian Islands, planning to arrive on September 1 after an overnight flight expected to last about 26 hours. The first PN-9 to depart loses oil pressure and is forced down 300 mi from San Francisco; the destroyer rescues its crew and tows it back to port. The second plane to depart, piloted by Commander John Rodgers, is forced down in the Pacific Ocean on September 1 after flying 1,841.12 mi nonstop. Rodgers and his three crewmen then sail the aircraft as a boat 450 nmi farther toward Hawaii before the U.S. Navy submarine picks them up 10 nmi north of Kauai on September 10. Although unsuccessful, their flight sets a world nonstop distance record for Class C seaplanes which will stand until 1930.

September

She is the only European aviation ship to see combat between the end of the Russian Civil War and the beginning of World War II.

He will die of his injuries on October 21, the first professional athlete killed as the result of a plane crash.
• October 19 – Frank T. Courtney makes the first flight in the United Kingdom by a rotary-wing aircraft, demonstrating the Cierva C.4 autogiro for the Royal Aircraft Establishment near Farnborough Airfield.
• October 25 – A storm with 80 mph winds strikes Bay Shore Park in Maryland on the Chesapeake Bay, where the United States Navy has moored 23 Curtiss SC-1 biplane floatplanes, planning to fly them in an air show demonstration during the next day's Schneider Trophy race. The gale breaks the 3 in mooring lines of 17 of the floatplanes, which then are dashed against seawalls or the shore. Seven of the planes are destroyed and 10 damaged. The 26 October afternoon edition of the Baltimore Evening Sun has the headline "Plane Disaster in Harbor Called Hard Blow to Navy" and quotes United States Army Air Service Brigadier General William "Billy" Mitchell, who calls the loss of the CS-1s "staggering" and blames it on U.S. Navy mismanagement of its aviation program.

Flight describes the journey as "the most extensive aerial tour on record."
