Commercial aviation has undergone enormous changes since the 1950s and 1960s. Aircraft have become safer, more efficient, and capable of flying longer distances than ever before.
Passenger expectations have changed as well. Modern travelers prioritize health, safety, air quality, and comfort. Advances in cabin filtration systems help maintain cleaner air throughout flights, while strict regulations govern onboard environments.
Smoking restrictions began appearing on certain routes during the 1980s. Over time, more countries introduced comprehensive bans. Eventually, smoking disappeared entirely from most commercial flights around the world.
The transition reflected broader public health initiatives taking place across many industries. Similar changes occurred in restaurants, workplaces, shopping centers, and other public spaces.
For younger generations, it can be difficult to imagine a time when smoking was permitted during international flights lasting several hours.
