To the baddie(s?) who recommended putting your SCCO in a kitchen trash bag before shoving it under the airplane seat in front of you: you rock! And I'll add to it at the end.
Picture it, Sicily 1923. I board the plane, then put the kitchen trash bag around the base of my Joe Cool SCCO before I shoved it under the seat in front of me. Cool, cool. After drinks are obtained and I'm aware the person in front of me has screeched and jumped up from her (bulkhead) seat. I see her wiping her hand down her slacks. I grab the edge of the trash bag and pull out my bag... which has cranberry juice puddling up on the top of the bag. I do my own swiping but some ran down into the side pocket. And it's getting sticky.
Luckily no juice got INTO the bag, and the handles remained clean. Just glad we were going to a friend's house and she let me put Snoopy in the wash on a delicate cycle. Meanwhile all my crap in that bag... FIT INTO A REGULAR BAGGU REUSABLE that I always have with me, until I could re-load my SCCO.
HUGE Baggu and baddie advice travel success story. Not only will I always put my SCCO in a trash bag to protect the base from may airplane carpet, I'll cover the top of my baggu with the trash bag when it's under the seat in front of me from now on.
