US Airlines Say Smaller Carry-Ons Are Not In the Cards
New submitter callgen writes: Airlines for America, a trade group for U.S. carriers, has rejected proposed international standards for carry-on bags. Last week, the International Air Transport Association (IATA) announced an initiative to "optimize" airlines' accommodation of carry-on bags by suggesting a new standard luggage size. It suggested a standard of 55cm x 35cm x 19cm, 58% of the size that Southwest allows. Most standard carry-ons are larger than IATA's recommendations, meaning travelers would have to purchase new luggage if the smaller size was adopted.
Thing is, while I do agree that a standard unit that allows for easy conversion has its advantages, the Metric System's units do not correlate well to real-world situations. 0 degrees Fahrenheit through 100 degrees Fahrenheit correspond well with the temperature range at which a human can work outdoors without resorting to special equipment. A foot, as it is similar to the anatomical part of the same name, is sized conveniently to work with in the physical world with things that the average person will interact with in arms-reach. A gallon of water is about at the limit of what most people can pour and handle in drinkable liquid.
As someone who grew up within the Metric system, I have the same issues with the imperial units. I find them completely unintuitive and out of my normal experience. What good is a foot as a unit? There is barely anything that is a foot long, except a foot. But the working space on my desk is 1 meter wide. The distance from my desk to the wall behind me has to be at least 1 meter to allow me to sit behind my desk. The length of my legs from the hips down is about 1 meter. What good is Fahrenheit either? When my thermometer shows 0 Celsius, I know I have to drive carefully, as the roads might be frozen. Much easier to remember than 32 F. 20 Celsius is a nice spring day, 25 Celsius means I don't need a jacket, and 30 Celsius means it's getting hot outside. Nice, round numbers. But 68 F, 77 F and 86 F? Horrible! 1 Liter of any drinkable liquid weighs 1 kilogram. That's easy. How much pounds is that? And why the difference between liquid ounces and weigh ounces? Catastrophic! 1 km is the distance I walk within 10 minutes. Easy. A mile? Something about 16 minutes. 100 km is the distance I drive within one hour on the Autobahn, even including heavy traffic. Easy. 100 miles? Yeah, one and a half hour, maybe a little more. How inconvient!
Metric works well with my experience. Metric works for me. Imperial units do not.
See how it boils down to whatever you grew up with? Imperial units are in no way more or less intuitive than metric ones. You just remember the real world examples that fit within the imperial units. I remember the real world examples that work well with metric units. None of them is more natural than the other one.
