Yeah, higher, plus you're 8,350 ft. farther from the center of the earth so gravity is less.
A major test was done on a commercial airline a few years ago. They tested flights going east, west, north, south. At an altitude of 38,000 feet, the average adult weighed about a lb less than they did on the ground at sea level, or somewhere around half a percent. Which could also be water lost in a few hours. I appreciate the tongue-in-cheek response though.
