In the 1930s, female flight attendants, then called stewardesses, were first introduced to make flying more comfortable. Their roles were similar to current-day flight attendants.
However, the first African-American flight attendant, Ruth Carol Taylor, didn't take to the skies until 1958.
Not only was the service better than in the 1920s, but airplanes themselves had become more comfortable. They were soundproofed, heated, and the seats were upholstered.
The planes could also fly much higher, reaching an altitude of around 20,000 feet, which reduced turbulence and made travel by aircraft a lot faster (around 200 mph).
The first pressurized commercial transport aircraft was introduced in 1938.
Cabins were also roomier, and seating was more creative with couches, reclining chairs, and swiveling seats.
