I rarely post here so I am not the smartest
anyways I was testing out whether a 747-400 would be worse than a 747-300 and turns out I was wrong. I am not sure why. For both aircraft I chose engines that had the least amount of fuel used (circled in red). For a 747-400 it has a slightly higher fuel consumption than the -300 but has better economics. Any reason why? Sorry if it is a dumb question.

Now yes it is obv on what is the seat config so I uploaded that. It's almost the same with the difference being the 747-400 has first class seats and the 747-300 doesn't and has an extra 10 more seats in economy
