As sustainability becomes a driving force in aviation, the question arises: between the Airbus A380 and the Boeing 747, which aircraft gets more miles per gallon (mpg)? While the Boeing 747 revolutionized air travel in the 1970s, the Airbus A380 pushed passenger capacity to new heights in the 2000s. A Quick VerdictIn simple terms, the Airbus A380 typically achieves better fuel efficiency per seat mile than most variants of the Boeing 747, particularly the earlier 747-400.
