Braniff International Airways ends its Concorde service. Inaugurated in January 1979, it involved an interchange service allowing the Concorde to operate over the United States by having Air France and British Airways crews fly the aircraft from Europe to Washington Dulles International Airport in Virginia outside Washington, D.C., where the aircraft were temporarily leased and re-registered to Braniff and flown by Braniff crews as Braniff aircraft to Dallas-Fort Worth Regional Airport. The process was reversed on the return trip, with Braniff crews flying the planes as Braniff aircraft to Washington Dulles, where they were "sold" back and re-registered to Air France and British Airways before being flown back to Europe by French and British crews. Braniff finds that its Concordes generally carry only 15 passengers per trip (about 20 percent of capacity) on the Dallas-Washington route, in sharp contrast to its Boeing 727s, which are full on the same route, and thus decides to discontinue its Concorde operations. Braniff is the only American airline ever to operate the Concorde.

After four hours on the ground in Havana, the DC-10 takes off early on August 15 and continues its flight to San Juan.
Representatives of 17 airlines meet with officials of the U.S. Federal Bureau of Investigation, U.S. Federal Aviation Administration, and the Public Safety Department of Dade County, Florida, to discuss ways of addressing the new wave of airliner hijackings from the United States to Cuba, which began on June 12, 1979. The renewed use of "behavioral profiles" to identify hijackers based on their personalities and behaviors is among the options they consider.
 August 16 – A record three hijackings of U.S. airliners take place on the same day. First, six Latin men threatening to ignite a fluid they said was explosive commandeer Eastern Air Lines Flight 90, a Boeing 727 with 53 people on board flying from Miami to Orlando, Florida. Later in the afternoon, four Latin men armed with bottles they say contain inflammable liquids take control of Republic Airlines Flight 228, a Douglas DC-9 with 116 people on board flying from Miami to Orlando. A half-hour after that, three Latin men threaten to ignite four containers they say contain gasoline (petrol) aboard Delta Air Lines Flight 1065, a Lockheed L-1011 Tristar with 183 people on board flying from San Juan, Puerto Rico, to Miami.

Engine shutdown takes another 3 minutes 15 seconds, by which time all or most of the passengers and crew apparently have been overcome by smoke and fire. By the time airport emergency personnel get one of the planes doors open 23 minutes after engine shutdown, all 301 people on board have died. It remains the second-deadliest single-aircraft accident in history, the deadliest in Saudi Arabian history, and the deadliest involving an L-1011.

August 29 – As passengers board Braniff International Airways Flight 920 – a Douglas DC-8 flying from Rio de Janeiro, Brazil, to Los Angeles, California – during a refueling stop at Jorge Chávez International Airport in Lima, Peru, Cuban refugees break windows in the airport terminal, rush onto the tarmac, and storm the plane, demanding to be flown to the United States. Although Peruvian Civil Guard officers fire shots in the air and prevent some refugees from boarding, 168 refugees join 17 passengers on board the airliner, and about another 150 refugees mill around outside the plane. With no crew aboard the DC-8 to fly it anywhere, negotiations result in the refugees surrendering to the Peruvian authorities. Two refugees suffer minor gunshot wounds during the incident when Civil Guard officers fire at them, and other refugees are cut by broken glass while breaking windows in the terminal.

Roberto will die in October 2002, but Miguel will return to the United States illegally in 2000 and finally will be arrested for the hijacking by U.S. authorities when he arrives for an appointment with the U.S. Immigration and Naturalization Service in Miami, Florida, in August 2002.

Deadliest crash
The deadliest crash of this year is considered an unusual accident: Saudia Flight 163, a Lockheed L1011 Tristar, caught on fire in the air shortly after departing Riyadh, Saudi Arabia on 19 August; the aircraft landed and came to a halt near Riyadh's runway but in failing to evacuate promptly, the fire overcame the passengers and crew killing all 301 people on board.
