The newest FAA regulations calculating standard passenger weight + carryon at 195lbs instead of 170lbs. Every time a passenger is forced to check a bag because it won’t fit in the overhead bin, this adds weight to the cargo hold. The final weight for a flight may be calculated as much as 1400lbs higher when passengers can’t carry on their bags. This allows less room for fuel and may even lead to lower capacity as airlines are forced to leave seats empty.
What can be done to improve carryon capabilities? By installing modified bins that provide more storage space, airlines can keep 34-40 more bags in the aircraft cabin. This can save as much as 900lbs for the CRJ700 or 1400lbs for the CRJ900.
