Your Beauty Products

Step 1: Opt for travel-size multitaskers. Choose a tinted moisturizer that serves as foundation, a soap and shampoo in one, and wipes that clean hands and face. (If you’re flying with a carry-on, check current regulations for liquids at www.tsa.gov.

Step 2: Fill empty bottles with your favorite brands. Evelyn Hannon, creator of www.journeywoman.com, a travel-advice website, swears by Japonesque’s Gotta Go Weekend Travel Bag ($20, www.amazon.com). A mere four inches high by four inches wide, it’s stocked with eight clear containers for lotions, contact-lens solution, and the like. Fill them three-quarters full. “The storage department on a plane is not pressurized, so items filled all the way to the top will overflow,” says Bond, who learned that the hard way when a sample of Pepto-Bismol exploded all over her clothes.

Step 3: Protect your belongings from ugly mishaps. Denise Boyd, a flight attendant for JetBlue, slips socks over her coarsely bristled brushes that “can tear into clothes and cause snags.”

Step 4: Group similar products in sealed resealable bags. Designate one sack for your cosmetics, one for your hair products, and one for skin-related items. Tuck the bags in the side corners of your suitcase or in a zippered outside pocket.

Your Jewelry

Stow inexpensive pieces in a seven day plastic pillbox. Or store them in a 35-millimeter film container lined with tissue. If you must take precious gems, wear them during your travels to reduce the risk of loss or theft, suggests Gilford.

Your Breakables

Wrap fragile items in sturdy clothing. Place them in the center of your bag surrounded by a buffer, says Laura McHolm of NorthStar Moving, a Los Angeles–based company that relocates 5,000 people (and their precious porcelain) each year. If you’re carting liquor bottles, secure them in the bottom center of your bag.

Your Dirty Laundry

Shrink it. Jessica Ellis, a graphic designer who travels between New York City and Chicago every other week, piles clothing into Eagle Creek Pack-It Compressor bags ($10 to $18, www.rei.com). “Zipper them, and they take out 80 percent of the volume.” Warning: This can have wrinkly consequences, so if the clothes don’t yet require laundering, lay them flat and place fabric-softener sheets between them. Consider your fresh-smelling clothes a welcome-home present.
