I’ll be flying shortly for the first time since the Christmas carry-on crisis so have been looking for ways to make my flight easier. My usual advice to skip the travel-sized toiletries (it takes a lot less packaging overall to simply take regular sized versions!) doesn’t fly in the face of the new regulations. So…with quick-thinking marketers such as this one gearing up to sell travelers and commitment-phobes pint-sized potions, I’m adjusting my advice. Go ahead, I say, and buy those adorable little bottles. But make sure they’re easily refillable. That way, you can hang on to them and refill them before each trip. Kudos to 3floz.com for ensuring there are plenty of organic offerings among their baby-sized brands. But uber-kudos (not to mention savings!) to you for reusing those cute containers and refilling from big bottles.

What’s more, keeping your own carryon light (and not bothering to check bags) means less greenhouse gas emissions. The lighter the load, the less fuel burned to fly.
