OP here:

Okay, "germs" may not have been the right word for the concern. I was trying not to be too descriptive and gross. The airline blankets I've opened in the past, on international flights, had hairs throughout and some kind of stuff smeared and dried in patches. It could have been food or maybe not.

For those not worried about "germs", or whatever, since, yes, they're everywhere- would you sleep in a hotel bed that was like the blankets I've encountered?

Maybe they're not like that anymore? Maybe that only happens in coach, I don't know? I was just wondering if others carried their own and how and what they did carry.

(: I love the Snuggie idea ha!
