Does 50 pounds weigh the same amount everywhere?: An airline math story
Whenever I've played the "watch the scale game" at an airline check-in, seeing if I'm a winner without going over 50, the magic number, or if I'll have to pull over to the side and repack, it has never occurred to me that the scale might be off.
According to a airline passenger letter that travel columnist Christopher Elliot received and posted on his blog, one Shawn Rabin discovered that his wife's suitcase magically changed weight between Phoenix and Chicago. Not only is Chicago a top 10 destination this summer, but evidently, according to an American Airlines scale, items weigh more there.
Rabin weighed the suitcase at home before he arrived at the Phoenix airport and it weighed 45 pounds. At the airport it weighed 44 pounds. So far, so good, particularly if Rabin and his wife want to feel like they weigh less than they do. Their scale at home weighs one pound heavier. However, by the time the suitcase spent time in Chicago before ending up at the American Airline check-in counter there, the suitcase picked up six pounds. The scale said it weighed 52 pounds which cost Rabin's family $50.
Before you yell out, " souvenirs stupid," consider this. According to Rabin, it was exactly the same suitcase with exactly the same things in it. The suitcase was again weighed in Phoenix after it made it back there and it had dropped down to 47.5 pounds along the way.
American Airlines, according to the letter Rabin received and Elliot posted, did give Rabin a $50 travel voucher for his family's next trip to make them feel happier about American Airlines, but the airlines didn't admit that the Chicago scale was wrong.
This story reminded me of a travel tip. When checking in bags, have a canvas bag of some sort, or even a plastic shopping bag handy. If you pull out a pair of shoes, and perhaps one other item, you'll get that weight down by two pounds easy. Sling the canvas bag over you shoulder. Still, it would be nice to be able to trust the scales for sure.
This reminds me of the sharecroppers stories when they used to go up against the big guy during harvest time. A dishonest landowner would have weights that were off in order to tip the scale in his favor when it came to paying out. Not that that's what airlines are doing, but perhaps this is a modern day version of a tale told through time.

Phoenix is very dry, Chicago is humid, I can see the suitcase and clothes picking up some weight just from the moisture in the air.

So what you are saying is that it could have picked up about 8-1/2 cups of water in humidity alone. Boy that is dry....American is lax at best and patently dishonest at the worst. It isn't that hard to calibrate a scale and even "inaccurate" industrial scales that we use are good to +/- 1lb over 7,000 lbs. As much as I hate to say it, some should file a class-action suit against them. That seems to be the only way that these companies pay attention.

As a photographer who travels with a case that always has the same stuff in it, I've seen differences of eight pounds at different airports. It's always over 50, so it doesn't matter to my wallet, but I've seen it range from 56 to 64 pounds, depending on the airline and the airport (United's scales almost always show the bag weighing more).

I work for a business that has scales that are checked by the city annually. We can't trade with the public without the seal that proves that our scales are accurate. Perhaps it is time for an airline watchdog group to suggest an annual inspection of these scales especially since the airlines are charging more for overweight bags.
I worked for the TSA for a while (2002-2003) and saw the way passengers and airline employees alike abuse the scales. Electronic and spring loaded scales need to be checked periodically to make sure they are balanced and weighing properly. If a scale is not level, it can affect the weigh by 5 pounds easily. There is no way a bag became 8 pounds heavier by humidity. Someone could have had their foot on the scale or been pushing down to view the weight and affected the number.
