I travel a lot between the USA and South Africa (very long flights), and on my most recent trip I bought the Shielo Hydrate Refreshing Mist at duty free to see if it helps with the beating my skin takes from the dry airplane air. It was great, and every time I used it I felt refreshed. It is also so easy to apply, I just did it right there in my seat and didn't even have to get up. Since I got back, I've kept on using it, because my skin feels super soft, and I'm now looking into buying the rest of the Shielo skin series.
