In 2005 the FAA had to raise the standard weight estimation used to calculate passenger weight to 190 lb per passenger instead of 170. That was 13 years ago. So I wonder how many planes are taking off today in the US that are over weight simply because so many more people today are >190 lb. The last flight I was on (out of the midwest and heading south) was scary on take off. It looked like it took nearly the whole runway to get up in the air and I'd say 90% of the passengers were at least 200 lb, many >250 lb.  Unless I have to go out of country I'll probably never fly again.
