If you want to take a quick nap on your flight, you'll have to pay up if you want to use a pillow from some airlines.
US Airways charges $7 for what's called a Power-Nap Sack. The package is an upgrade from a standard issue pillow. It includes a blanket, inflatable neck pillow, eyeshades and an earplug. It also includes a coupon for a future purchase from SkyMall, an in-flight shopping catalog.
American Airlines has a similar blanket and pillow package for $8.
The new products are nice and convenient, but if you don't want to pay this travel fee, you'll have to figure out a way to nap without an airline-issued cushion.
