Hopefully everyone uses what works best for them.
Before leaving the house to fly, I have a full page list.
For Pre-take off and landing, written is the only way for me. I can't
remember how to spell actual words let alone acronyms, so I combined
Schliecher's and Tom's, then broke into four parts pasted below:

Some items are there to guarantee the flight is comfortable and hassle
free. About 1 in 10 flights I go back to get something from the car or
hanger after I'm gridded.

I also have a short "don't leave the house w/o it" list taped to the
fridge, my friends use it to confirm that I'm a dork.
