7Sage has a bunch of hour long videos on podcast apps like Himalaya. Some of those videos cover major points in the core curriculum. You could download those podcasts and listen on the plane.
The courses on here will take you through the Core Curriculum, which is helpful. ThinkingLSAT has a series with FUNdamentals for each section so if you like podcasts maybe try it. And LSATUnplugged on YouTube has helpful teaching.

Yet if you wanted to, you might find it beneficial to listen to LSAT podcasts when the 4ish hours are up and you can still get a lot out of the good ones. Don't give up!
