Do you have any tips for my flight to DeKalb?
We've pulled together all the info you need to make your journey an enjoyable experience. Follow our tips and you'll be cruising through airport security and exploring DeKalb in no time at all. What to pack in your hand luggage:

  • Travelling on a plane can be easy if you've got all the right things. Firstly, you'll want a few basic toiletries, such as a toothbrush and hairbrush, a spare change of clothes and a good book. Secondly, leave space in your bag for your laptop, a charger, any daily medications and perhaps a proper neck pillow too. Last, but definitely not least, be sure to take your passport, travel docs and your bank cards.

Do not pack the following items in your hand luggage:

  • While the list of restricted items can differ between airlines, the general rule to follow is nothing sharp, flammable or explosive. This includes things like screwdrivers, pocket knives, spray paint and flares. Sporting equipment like golf clubs, and items that could harm other people, such as firearms and ammunition, aren't allowed in the cabin either.

What to wear on a flight:

  • Comfort should be your top priority when deciding what to wear on board. Loose, breathable clothing is a smart choice, as are enclosed shoes like sneakers.
  • Deep vein thrombosis (DVT), a blood clotting condition caused by prolonged periods of inactivity, can be a risk on long-haul flights. Try to walk around the cabin and stretch your legs or do some gentle exercises in your seat to improve your circulation.

How to get through airport security fast when flying to DeKalb?
As savvy travellers know, the secret is to be organised before you arrive at airport security. That way, you'll be stepping onto that plane to DeKalb in the blink of an eye. Follow these tips and get your trip off to a great start:

  • Your boarding pass and passport will need to be inspected by airport security. Keep them handy so you don't hold up the line.
  • Time to strip down. Well sort of. Your coat, belt, keys and other small items, like your headphones, will need to go through the X-ray machine. Make the whole process faster by removing them before your turn.
  • For just a few minutes, you'll have to unplug from the digital world. Your phone, tablet and any other electronic gadgets must also go through the scanner.
  • Remove all gels and liquids from your hand luggage. They usually need to be sent through the X-ray machine separately. Each product should be no larger than 3.4 ounces (100 millilitres) and everything must fit in a single quart-size (one litre), clear zip-lock bag.
  • The right choice of footwear can save you a few precious minutes. Boots and heavy shoes are often required to be removed and X-rayed separately. Slip-on shoes are usually not.
  • Sharp items are prohibited in the cabin. They'll be confiscated at security, so put them in your checked suitcase.
