1. Expandable Carry-Ons

The most essential item a business traveler needs is an expandable carry-on. One size does not fit all your needs for business trips. On long trips, you may find you need extra space for another set of clothes. Maybe you don't need the extra space going to your destination, but coming back you may be bringing presentation materials or swag from a conference.

2. Hand Sanitizer

Business travelers should always have hand sanitizer, as you will encounter high-touch surfaces in the plane, hotel, and offices. Those high-touch areas are sources for germs, bacteria and viruses. Having hand sanitizer will make it easy to clean your hands, preventing you and others from becoming sick.

3. Battery Pack

A battery pack comes in handy when the outlet at the airport doesn't work, or you need a quick charge on-the-go. Look for chargers that can charge two devices to at the same time. For the environmentally friendly consumer, there are solar battery packs that can be powered up by the sun or standard electric outlet.

4. Extra Charging Cable

Most business travelers only bring one charging cable for their mobile devices. As many have found out, they tend to be lost or broken during a trip. Spend a little money on a backup of each type of charging cable your devices use. Buy your extra cable at a store outside the airport terminal because you maybe charged a premium price at the terminal store.

5. Mobile Hotspot

Mobile hotspots are great for the business traveler—they make it easy to connect to the internet. They are particularly useful when you don't have access to a public Wi-Fi network. Most hotspots allow you to connect multiple devices, which is great when travelling with a co-worker since both can work at the same time. Some cellular plans allow customers to use smartphones as a hotspot—check with your service provider to see if your plan has that option.

6. Travel Pillow

Getting proper sleep on a business trip is important to keep you energized and healthy. Travel pillows make the uncomfortable plane travel relaxing. The pillows are designed to give your head and neck the proper support they need for you to fall asleep. They are also easy to store in the front pocket of your carry-on.

7. Durable Notebook

As much as we all rely on technology, sometimes you must jot down notes quickly or organize your thoughts. Carry a durable notebook with you for those moments. Durable notebooks are more resilient to the rigors of travel then a normal notebook or notepad. They come in different sizes depending on what you need and can fit in your carry-on.

8. Collapsible Water Bottle

It's always good to keep hydrated on trips, and a collapsible water bottle will help with getting enough water while saving valuable space. The water bottle can contract to fit in your carry-on, and when ready to use, you can easily expand the bottle. Having one of these will also save money because you won't have to buy bottled water.

9. Business Card App

Business card apps are an essential not only for business travel but for everyday use. The app scans business cards capturing the information, then creates a contact on your smartphone. Now you don't have to manually put the information into your smartphone. Plus, you won't have to carry a stack of new business cards that you just acquired from your trip.

10. PreFlight Airport Parking App

Another app a business traveler should have is the PreFlight Airport Parking App. With the app, business travelers can make a profile, pay for a parking reservation, track reward points, and take advantage of discounts. It also comes in handy when you need to change you parking reservation on the fly. You can use it for any of our parking garage facilities located throughout the United States.
