The Consumerist, which we follow, has an article pointing out how while baggage fees are being more stringently enforced…when a news crew accompanied an official from the Arizona Department of Weights and Measures to inspect United Airlines scales, they found all but one to be off.
Airport scales, subject to a lot of use, are often found miscalibrated. In defense of the airlines…with the use and abuse heaped on them…it is not surprising. The calibration of these scales is a state responsibility in the United States…and we have no data as to the enforcement by state or in other countries…We welcome comment on this.
Now…when you visit a gas station for example, there is usual a sticker indicating the last time the gas pump was calibrated to ensure accuracy and to ensure you get the amount of gas you pay for. It would not be unreasonable for states to require a regular schedule and clearly labeled inspection stickers on all airport scales.
Airport scale miscalibration is not a crisis for most…who keep within baggage rules. In Europe, where airlines often charge excess by the pound or kilo, it can be a serious issue. In the United States, where airlines charge flat rate for any heavy bag…a one or two pound overage can mean $25-50.
Best advice to give…you do have the right, if you are over, to ask that your bags be weighed on at least one alternate airport scale…If they refuse, ask to see a manager.
