and because of the takeoff/landing and time to get up to it's probably closer to 2*11h, so yea assuming 3 hour layover that turned into 25 hours

Airports suck less than being on an airplane. Usually.

I can walk around, find something to eat or read, people watch. Plug in a laptop and sit at a table that's reasonably comfortable to work on. Relocate somewhere quieter, or more interesting. See if I can find bathrooms that aren't slammed. Get my steps in / some exercise.
