I've been using an anglers vest with multiple pockets to store stuff while flying. Works OK, but here in TN in the summer an additional layer of clothing is not what anybody wants. Ran across this. It's a car seat organizer called High Road Swing Away XL. Got it online at cargogear.com. I used 2 suction cups cable tied to straps that are on the organizer to hang it on the sidewall panel. Loaded it up with Ipad, phone, and a small bottle of water, seems to stay in place just fine. Total cost: Swing Away- $16.55; shipping- $2.95; suction cups- $3.25. Not bad for less than $23.
