I need some suggestions to read, watch, things to do etc, while on the plane.

My October travel schedule is pretty lol

Midwest to Vegas 7th-9th
Midwest to NYC 13th-16th
Midwest to Vegas 19th to 23rd
Midwest to LA 26th to 29th.

I like obscure documentaries, history books, pretty much open to anything.

By my count it is like 26 hours of flying, so any help would be appreciated.
