How to survive the flight to DeKalb?
We’ve rounded up all the info you need to make your journey as pain-free as possible. Follow our tips and you’ll be hightailing it through the airport and having a ball in DeKalb in no time at all.What to pack in your hand luggage:

  • Air travel can be easy if you bring the right things. Firstly, you’ll need basic toiletry items, such as deodorant and a toothbrush, a clean set of clothes and a magazine or two. Next, find a spot in your carry-on bag for your electronic devices, chargers, medications and maybe a proper neck pillow as well. Lastly, and most importantly, remember to bring your passport, travel docs and some cash.

Do not pack the following items in your hand luggage:

  • Put all your full-sized bottles of shampoo and conditioner in your checked baggage. Any liquids in your carry-on suitcase larger than 3.4 ounces (100 milliliters) will be confiscated. Sharp or pointed objects, like your trusty Swiss Army knife, and dangerous products which are explosive or flammable, such as aerosol cans, spray paint and fireworks, are also banned.

What to wear on a flight:

  • Your aim here is to feel as comfortable as you can. Layer yourself up in natural fibers and remember to bring a cardigan in case you get cold. Always go with roomy, flat shoes as it’s possible that your feet and ankles will swell during the flight. Leave the high heels and heavy boots in your checked luggage.
  • Unfortunately, a risk of long-distance flying is developing DVT (deep vein thrombosis), a blood clotting condition caused by lengthy periods of inactivity. To prevent this, make the most of every opportunity to wander around the cabin. Compression socks and tights are another simple way to help reduce this risk.

How to get through airport security fast when flying to DeKalb?
A little pre-planning before your flight can make your getaway to DeKalb a pleasure. Read through our handy tips for a speedy journey past security:

  • Airport security personnel first need to verify that you have a valid passport and travel documents before anything else. Keep them within easy reach.
  • After that, both you and your carry-on bag will be X-rayed. To make the process quick and painless, remove anything that is likely to set the alarm off. Personal belongings like your coat, belt and headphones need to go through the machine.
  • Your electronic gadgets like laptops and phones will also have to go on a tray to be scanned. No need to worry though, you’ll be back online before you know it.
  • Remember to remove liquids and gels from your hand luggage. They often need to be sent through the X-ray separately. Each product should be in a container no larger than 3.4 ounces (100 milliliters) and everything must fit in a quart-size (one liter), clear zip-lock bag.
  • It’s also likely that you’ll be asked to remove your shoes to be X-rayed, so wearing slip-on shoes is always a clever idea.
  • Avoid taking prohibited items in your carry-on bag. If you have any sharp objects like a pocket knife or tools, pack them safely away in your checked suitcase. They won’t be allowed in the cabin.
