Long lines at security checkpoints, tiny plastic cups of drink, small bags of biscuit, planes full of passengers, fees attached to every service—all reflect the realities of 21st century commercial air travel. It’s no wonder that many travelers have become nostalgic (怀旧) for the so-called “golden age” of air travel in the United States.

During the 1950s, airlines promoted commercial air travel; airline hostesses served full meals on real china, airline seats were large and frequently empty with enough legroom, and passengers were always dressed well.

After jets were introduced in the late 1950s, passengers could travel to even the most distant locations at speeds unimaginable a decade before. An airline trip from New York to London that could take up to 15 hours in the early 1950s could be made in less than seven hours by the early 1960s.

But the good memory of airline in that time can be tricky, and “golden ages” are seldom as beautiful as they seem. Until the introduction of jets in 1958, most of the nation’s commercial planes were propeller-driven (螺旋桨驱动) aircraft. Most of these planes were unpressurized, and with a maximum cruising (巡航) altitude of 10,000 to 12,000 feet, they were unable to fly over bad weather. Delays were frequent, turbulence (气流) was common, and air sickness bags were often needed. For much of this period, the old saying “Time to spare, go by air” still rang true.

Through the 1930s and into the 1940s, almost everyone flew first class. Airlines did encourage more people to fly in the 1950s and 1960s by introducing coach or tourist fares, but the savings were relative: less expensive than first class, but still pricey. Although the invention of jets did result in lower fares, the cost was still out of reach of most Americans.
