I bought my ipad to use whilst travelling, but right now theres no proper way to view it when you're flying. Heres my best attempt. Simple really
I cut two slits in a hard silicon ipad cover, and slid a velcro belt (i've actually used two connected together as just one won't fit round an aircraft seat) through the back cover near the top.
It holds up pretty good, but you might have to put something underneith it to angle it for a better view, I won't know until Thurs how good it really work.
