Yes, if you had a plane that was essentially a powered glider. Bart Rutan's Voyager that made its nonstop around-the-world flight was exactly that, and traveled about 25,000 miles on about 8300 lbs of fuel. At 6 lbs/gal, that's only 20 mpg, but they were hauling over 9000 lbs. of weight on a plane that only weighed 939 lbs empty.
