January 20 – Two months after the celebrated hijacking of Northwest Orient Flight 305 by a unidentified man who becomes popularly known as "D. B. Cooper", Hughes Airwest Flight 800 becomes the target of a copycat hijacker. After boarding at McCarran International Airport in Las Vegas, Nevada, 23-year-old Richard Charles La Point claims he has a bomb while the plane is on the taxiway and demands US$50,000 in cash, two parachutes, and a helmet. When his demands are met, La Point releases 51 Reno, Nevada-bound passengers and two flight attendants, after which the DC-9 takes off and flies eastward toward Denver, Colorado, followed by two United States Air ForceF-111 fighters. Without a coat and in cowboy boots, La Point bales out via the plane's lower aft door over the Eastern Plains in northeastern Colorado in mid-afternoon. The parachutes he had been given were high-visibility ones secretly equipped with emergency locater devices, and he sprainsis ankle on landing, making it impossible for him to move; he is apprehended a few hours later, with minor injuries and very cold. The plane, with two pilots and a flight attendant on board, lands safely at Denver's Stapleton International Airport at 2:55 pm MST.

As a Chalk's International AirlinesGrumman G-73 Mallardamphibian (registration N3010) refuels at Watson Island, Florida, during a flight from Miami, Florida, to Bimini with five passengers and a crew of two aboard, two members of the Black Liberation Army, Joseph Terron Bennett and James William Brewton, hijack it and demand to be flown to Cuba. When a Chalk's mechanic gets a .25-caliber pistol out of his car, intending to shoot out the plane's tires, they shoot and wound him. They then order the pilot to start the engines, but he refuses; they shoot him three times, and he jumps from the plane. A passenger also jumps out of the plane. With four passengers still aboard, Bennett and Brewton force the copilot to fly them to Havana, which – after bumping into a Grumman Goose parked beside it at Walton Island – the Mallard barely reaches with its fuel tank almost empty.

Believing that he is personally responsible for expelling Satan from the Earth and that he must hijack an airliner and receive a ransom as part of that mission, 29-year-old William Herbert Green gives a note saying he has a gun and demanding $500,000 in cash and to fly to the Bahamas and hands it to a flight attendant aboard Delta Air Lines Flight 952 – a Convair CV-880-22-2 flying from Chicago, Illinois, to Miami, Florida, with 92 people on board – telling her to pass it to the captain. After 40 minutes of negotiations between the captain and Green, Green agrees to allow the plane to return to Chicago, where he releases all the passengers. The captain then tells Green that he can either fly to the Bahamas and be imprisoned there, where he knows no one, or surrender right there in Chicago. Green decides to surrender in Chicago.

Armed with a .357 Magnumrevolver and carrying a parachute, 22-year-old Robb Heady barges onto United Airlines Flight 239 – a Boeing 727 with six people aboard at Reno, Nevada, preparing for a flight to San Francisco – and demands a $200,000 ransom. United Airlines borrows the money from two casinos, and Heady takes delivery of it on the tarmac while holding two flight attendants at gunpoint with their heads under a blanket, frustrating a U.S. Federal Bureau of Investigation (FBI) sniper who cannot distinguish their heads from Heady's. He then orders the plane to take off, but engine trouble prevents it from doing so. He boards another United Boeing 727, which does take off. As it flies over Nevada's Washoe Lake, Heady parachutes from the rear door, taking $155,000 of the ransom money with him. He drops the money during his descent and suffers injuries on landing. FBI agents arrest him early the next morning when he returns to his car, parked near the lake, which the FBI had staked out because it had a United States Parachute Associationbumper sticker on it.
June 8 – Two passengers, one armed with a gun, enter the cockpit of a Slov-AirLet L-410A Turbolet with 16 people on board during a domestic flight in Czechoslovakia from Mariánské Lázně to Prague, demanding to be taken to West Germany. They shoot and kill the pilot and threaten to shoot the copilot if he does not change course toward Munich, and the copilot tells them that the airliner lacks the range to reach Munich, but that he would fly into West Germany and land at the nearest large city in West Germany the plane can reach. Meanwhile, eight other passengers involved in the hijacking attack the four uninvolved passengers with bottles, to avoid any resistance from them in case one of them is a plainclothes security officer. After the hijackers see factory signs in German and Western cars on the roads below and are satisfied that the plane has reached West Germany, the copilot lands on a 600-meter (1,968-foot) airstrip at Weiding, West Germany. The hijackers – seven men and three women, one of them with an infant, escape, but they later are apprehended.

McNally commandeers American Airlines Flight 119 – a Boeing 727 with 101 people on board flying from St. Louis, Missouri, to Tulsa, Oklahoma – as it approaches Tulsa. He orders the airliner to return to St. Louis, demanding US$502,500 and five parachutes. He receives the money after the plane lands at Lambert–St. Louis International Airport in St. Louis. While the plane is on the ground, 30-year-old David J. Hanley becomes enraged by the hijacking while watching events unfold on television in the lounge of a Marriott hotel near the airport, drives his 1971 Cadillac through the airport's fence, and smashes it into the landing gear strut under the airliner's left wing at 80 mph (129 km/hr) at 12:30 a.m. on June 24. McNally demands another Boeing 727, and after it arrives, he walks to it hiding behind hostages to avoid being shot by police snipers. He orders the new plane to take off and fly northeast. At 2:50 a.m. on June 24, he parachutes from the plane at an altitude of 8,000 feet (2,438 meters) near Peru, Indiana, with what ransom money he has left after giving the flight attendants generous tips, but loses the money and his gun during his descent. He later is apprehended by police.

About halfway through the flight, he tells a stewardess that he wants $50,000 and a parachute, claiming he plans to jump out of the plane near Pocatello, Idaho. He does not mention having a weapon, so the captain continues the flight to Portland, where the captain orders the passengers to evacuate the airliner. Carre then surrenders quietly and is committed to a mental institution.
Absent without leave and armed with a pistol, United States Army helicopter crewman Francis Goodell hijacks Pacific Southwest Airlines Flight 389, a Boeing 727 flying from Oakland to Sacramento, California, with 58 people on board.

The plane flies to San Diego, California, where Goodell picks up the ransom and releases all the passengers except for a California Highway Patrol officer who volunteers to remain aboard as a hostage. As the plane returns to Oakland, where Goodell has demanded that a helicopter pick him up, his hostage warns him that when he disembarks from the airliner, FBI snipers will shoot him to death. Frightened, Goodell surrenders.

Armed with a sawed-off shotgun, a pistol, and a typewriter case they claim contains a bomb, Michael Stanley Green and Lulseged Tesfa hijack National Airlines Flight 496 – a Boeing 727 – as it flies from Philadelphia, Pennsylvania, to New York City with 113 people on board, demanding a ransom of US$600,000 and forcing the plane to return to Philadelphia, where they express a desire to flee to Mexico. During eight hours on the ground there, National Airlines gives them all the money it can raise – $500,000 plus $1,600 in Mexican pesos – and the pilot escapes, after which Green and Tesfa release the passengers and transfer to another Boeing 727 with sufficient range to take them to the United States Gulf Coast. The 727 takes off from Philadelphia and flies southwest with only the copilot, flight engineer, four female flight attendants, and the two hijackers aboard. It reaches Texas, passing over Dallas and then flying toward Houston. The hijackers decide rhat rhey want to go to Jamaica instead of Mexico, and by the time the plane is over the Gulf of Mexico it is desperately short of fuel, and it makes an emergency landing at Lake Jackson Dow Airport in Lake Jackson, Texas, blowing out two tires as the airliner brakes hard to avoid going off the end of the short runway. The copilot and flight engineer jump out of the plane, and, after four hours of negotiations during which the hijackers release one flight attendant and demand another plane while threatening to kill the three women still on board, the hijackers release them and surrender to the U.S. Federal Bureau of Investigation on July 13, 22 hours after the hijacking began.

During the evening of September 15, the hijackers permit six passengers to leave the plane for medical reasons. During the predawn hours of September 16, authorities bring the seven Croatian prisoners to the airport; one of them refuses to join the hijackers, but the other six board the airliner and the hijackers release 30 passengers in exchange. A few hours later, a police car delivers the ransom money to the hijackers, and they release the rest of the passengers and force the plane to fly to Madrid, Spain, carrying its crew of four and the nine Croatians.

Four days after killing an Arlington County, Virginia, police officer and a bank manager during a bank robbery, Charles A. Tuller, his teenage sons Bryce and Jonathan, and teenager William White Graham kill an Eastern Airlines ticket agent in Houston, hijack Eastern Airlines Flight 486 – a Boeing 727 with 13 passengers and a crew of seven aboard – there, and order it to be flown to Havana, Cuba. During the four-hour flight, which includes a refueling stop at New Orleans, Charles Tuller repeatedly harangues the 13 passengers aboard during the flight, saying he is a "white middle-class revolutionary" and that Cuba is "the only place that a person could enjoy the benefits of freedom", and threatening some of them with guns. The three Tullers will return to the United States in June 1975, calling life in Cuba "a living hell", and be arrested. Graham will return in the late 1970s and be arrested in 1993.
November 6 – Armed with a .38-caliber revolver and claiming to have two bombs, 47-year-old Tatsuji Nakaoka, wearing a mask and traveling under the pseudonym "Kozo Hotta," hijacks a Japan Air LinesBoeing 727 with 126 people on board shortly after it takes off from Tokyo's Haneda Airport for a domestic flight to Fukuoka, Japan. He forces the airliner to return to Haneda Airport, and demands $2 million in U.S. currency and that a Douglas DC-8 be provided to fly him to Cuba, stipulating that the DC-8 stop at Vancouver and in Mexico along the way. After receiving the ransom money, Nakaoka takes eight hostages and boards the DC-8, where several police officers hiding in the main cabin immediately overpower and arrest him.
November 10–12 – Seeking revenge against the City of Detroit, Michigan, for alleged police brutality and an arrest for sexual assault, Louis Moore and Henry Jackson join with Melvin Cale in hijackingSouthern Airways Flight 49, a Douglas DC-9 with 33 people aboard, during a flight from Birmingham to Montgomery, Alabama. Armed with guns and hand grenades, they demand 10 parachutes, 10 bulletproof vests, and a US$10 million ransom, and order the airliner to fly to Detroit to pick it up. Fog prevents a landing there, and the plane diverts to Cleveland, Ohio, while the hijackers consume the plane's liquor supply. They then order the plane to fly on to Toronto, Ontario, Canada, where Southern Airways offers them US$500,000. Moore rejects this and orders the plane to take off again and fly to Knoxville, Tennessee, but before arrival there orders the plane to circle the Oak Ridge National Laboratory, threatening to crash the plane into the nuclear reactor there unless his demands are not met. Southern Airways collects 150 pounds (68 kg) of cash totaling $2 million, and gives it to the hijackers when the airliner lands at Chattanooga, Tennessee, hoping the hijackers will be too impressed by the physical amount of cash to realize it is less than they demanded. The ruse works, and the jubilant hijackers hand out cash to the passengers and crew, but then order the plane to fly to Havana, Cuba, where authorities refuse to allow the hijackers to disembark. The airliner takes off again, stops at Key West, Florida, and then lands at a United States Air Force base near Orlando, Florida, where Federal Bureau of Investigation agents damage its landing gear with gunfire. It again flies to Havana, arriving there on November 12, and Cuban authorities arrest and jail the hijackers and impound the ransom for return to Southern Airways. The hijacking prompts a change of heart among airlines and transportation authorities in the United States, who previously had viewed hijacking as a relatively benign interference in their business which rarely resulted in harm to anyone and not worth the inconvenience and expense of preventing it, and leads to the requirement to screen all passengers boarding airliners in the United States beginning in January 1973.
November 15 – The first attempted aircraft hijacking in Australia takes place when Miloslav Hrabinec attempts to hijack Ansett Airlines Flight 232, a Fokker F27 Friendship with 31 other people on board, as it is descending to land at Alice Springs.

After landing at Alice Springs, he releases 22 passengers, then threatens to begin shooting the rest of the people on board if not given a light plane, a pilot, and a parachute. After he leaves the Fokker to approach the light plane with a flight attendant as a hostage, he wounds a policeman, is brought under fire by police, and then shoots himself to death.
November 22 – While U.S. Air Force B-52 Stratofortresses fly their heaviest raids of the Vietnam War at the time during the day, a North Vietnamese surface-to-air missile hits a B-52 over North Vietnam near Vinh; its crew manages to fly it to Thailand before ejecting.

December 14 – Twenty-one-year-old Larry Stanford pulls a .22-caliber rifle out of his coat while boarding Quebecair Flight 321 – a BAC One-Eleven scheduled to make a domestic flight in Canada from Wabush, Newfoundland, to Montreal, Quebec, with a scheduled stop at Quebec City, Quebec – and brandishes it at passengers. After 20 minutes, he orders the pilot to take off and fly directly to Montreal without stopping at Quebec City. At Montreal, he releases all 52 passengers and a stewardess, then demands that the plane fly to Ottawa, Ontario, Canada. After 15 minutes on the ground at Ottawa, he orders it to fly back to Montreal, where he meets with his father and a psychiatrist aboard the plane, then surrenders peacefully.
