This crisis forced airlines to search for ways to save on fuel costs, which led to a gradual reduction in cruising speeds. For example, the Boeing 707, a popular airliner in the 1960s, had a cruising speed of around 600 mph (966 km/h).

Flying became more and more common in the 1960s. Passengers didn't dress up as much as before, though they typically dressed up more than passengers do today. Passengers flying in the 1960s could also fly without any form of ID, HuffPost reported.
According to Drela, today's airplane builders actually favor a smaller, lighter, and therefore slower aircraft that peaks its fuel efficiency at slower speeds. (Cars also become more efficient at slower speeds on highways.)
Cruising speeds for commercial airliners now range between about 480 and 510 knots, compared to 525 knots for the Boeing 707 during the 1960's, according to a 2014 article from the MIT School Of Engineering.
+ * 57,700,000 passengers carried in 1960, up 3,000,000 over 1959-as compared with a gain of some 7,000,000 the previous year. 38.8 billion revenue passenger-miles in 1960, up 2.5 billion over 1959-as compared with a gain of 5 billion the previous year.
First aircraft to exceed 160 km/h (100 mph) in level flight: Maurice Prévost flew a Deperdussin Monocoque in the 1913 Gordon Bennett Trophy race averaging over 160 km/h (100 mph) during a lap on September 28, 1913.
Flying Is Only Getting Safer Over TimeGlobal flight accident rates have been steadily declining over the years for a number of reasons, according to the International Civil Aviation Organization (ICAO).
Despite being known as the golden age of air travel, flying in the '50s was not cheap. In fact, a roundtrip flight from Chicago to Phoenix could cost today's equivalent of $1,168 when adjusted for inflation.
The ICAO attributes the improvements in safety to the safety commitments shared across the industry. In fact, the trend across many years of aviation is that, today, it is safer than ever to fly.
Chou did the math, and it turns out that frequent fliers actually age the tiniest bit more quickly than those of us with both feet on the ground. Planes travel at high enough altitudes that the weak gravitational field speeds up the tick rate of a clock on board more than the high speeds slow it down.
Duty cycles differ. Two thousand car hours typically represent between 70,000 and 100,000 miles, about half the car's expected life. With a piston-airplane engine, 2,000 hours is about all we expect. On the other hand, the car will run out that mileage in five to seven years; a GA airplane will last 40.
On average, an aircraft is operable for about 30 years before it has to be retired. A Boeing 747 can endure about 35,000 pressurization cycles and flights—roughly 135,000 to 165,000 flight hours—before metal fatigue sets in.
With proper maintenance and repair, an aircraft can last longer than its estimated lifespan. On average, commercial aircraft can last between 20 to 30 years. However, airlines often retire their planes earlier due to economic and operational reasons.
