This advice is twofold: Wear layers and pack in layers. First, your on-the-road wardrobe should feature plenty of layers, which will help you jetset through multiple climates in style and comfort. Second, the items in your bag should be packed in neat layers for easy screening. According to the TSA, "Pack items in layers (shoes one layer, clothes one layer, electronics one layer, etc.)" so that the security agent screening your bag can get a clear picture of what's inside. The faster the TSA agent can screen your stuff, the faster you'll get through the security line.
Asking is the quickest way to get a discount but it’s also the quickest possible way to piss off an Airbnb host. This is what differentiates the pros from the newbies. My general policy as a host — which I’ve been doing since 2011 — is to turn away hagglers because it signals a problem guest. It’s still possible, though, to get a confirmed booking and save some money without irritating a host so much they end up declining a guest’s inquiry outright. The trick is learning how to do it delicately.
“I’m a firm believer that everything you need for a trip — whether it be three days or three weeks — should be able to be packed in a carry-on. This is simple once you master the art of layering your clothes. Choose a color combination for your attire and pack only pieces that match this so that you can mix, match and layer to create different looks (instead of packing completely separate outfits).”
