I love your suggestions, but I want to strongly caution against #73. I’m a retired chemist from the pharmaceutical industry, and I can tell you that prescription drugs sold in blister packs are that way for a very good reason; not simply because pharma likes higher manufacturing and shipping costs. They are that way because the drugs require them for stability, generally because of moisture, UV, or even atmospheric oxygen. Best case, they lose potency. Worst case, they create toxic degradation products. I personally take drugs out of the box, but not the blisters, and store them where they won’t get a lot of light and heat.
To be able to avoid checking in your luggage, you’ll have to pack strategically. It might be a business trip, but you are also excited to explore the sights and let your hair down afterwards. Gather your most versatile clothing. Bring shoes that look sharp in the meeting room but can also hold up to a night on the dance floor. A semi-formal, single-color blazer makes a perfect multipurpose fashion piece, functioning as half of your business suit during the day and a nice accompaniment with jeans for the evening.
Choosing lightweight suitcases not only makes it easier for you to get about, it also often gives you more space to pack. At 8.8 pounds, Eagle Creek's Hovercraft 25 features an expandable main compartment that adds an extra 15 percent capacity. If you're planning on doing lots of shopping during your trip, pack an extra travel tote or daypack that folds flat in your luggage—it can even double as a place to carry essentials on day outings and bring back your travel treasures on the flight back. Patagonia offers an extra-lightweight travel tote that you can hand-carry or wear as a backpack, then stuff into its own pocket when it's no longer needed.
"Choosing thin clothing that packs flat over thicker, more bulky items makes a huge difference in how much you can fit in your suitcase," says Susan Foster, author of Smart Packing for Today's Traveler. Instead of packing a heavy sweater and jeans, try more travel-friendly options like a micro-fleece pullover and pants in lightweight, weather-resistant fabric. Diana Lane, an associate with Geiger & Associates, a Florida-based destination marketing firm, loves the versatility of lightweight sarongs, which can be worn as skirts, various styles of dresses, shawls, swimsuit coverups, shoulder bags or even used as a blanket. "There aren't many items that give us quite this much bang for the buck," she says.
Now, remember, we skipped the cocktail in the airport. We’re going to skip it again now. Traveling, especially onboard airplanes, can be extremely dehydrating. So, to put it one way, it’s best to not “drink and fly,” unless what you’re drinking is water. The air itself on the plane is also quite dry, so beyond hydrating, many travelers opt to bring moisturizers, eye-drops, and lip balms as well.
This is always my number-one travel tip -- there are just so many benefits and so few downsides to taking less stuff with you when you travel. When we first set off on our travels, we maxed out the full baggage allowance, and it slowed us down. Carrying so much also caused various types of pain and annoyance: actual physical back pain, the irritation of having to lug around a whole lot of not-so-useful gear, the difficulty of finding somewhere to store our stuff on transit days.
The Bundle Approach: This ingenious method of packing, which we learned from Judith Guilford, co-founder of the Easy Going travel store and author of The Packing Book, has now become our favorite. It’s a bit difficult to explain without a demonstration, but we’ll do our best. You need luggage that opens up and lies flat to do this. You will also need a flat, soft, pouch-like rectangular “core” with dimensions that are at least 1/2 to 3/4 the size of your luggage compartment. This can be a pouch filled with underwear or something similar.
It also helps to know which items are, according to the TSA, considered liquids or gels and thereby subject to the 3-1-1 rule. This isn't as simple as it sounds. Foods such as peanut butter, pudding, mashed potatoes, and icing are classified as gels. Mascara, lip gloss, and aerosol items are also classified as liquids or gels. But keep in mind that liquid prescription medication is exempt. (Read more on that on The TSA Blog.) See a more complete list of liquids and gels that are not permitted in carry-on luggage in quantities greater than 3.4 ounces here.
Invest in Luggage: After you figure out if you will be a “carry-on only” or “check only” type of business traveler, invest in a lightweight, durable piece of luggage that has a warranty. The same goes for a laptop bag. Whether you choose a shoulder bag or backpack, make sure it has a lot of padding and distributes weight evenly. You do not want your luggage breaking in the middle of an airport.
