Do you have any tips for my flight to Decatur?
We've rounded up all the info you need to make your flight an enjoyable experience. Follow our insider tips and you'll be hightailing it through the airport and seeing the best of Decatur in no time. What to pack in your hand luggage:
  • It's easy — first, put in your passport, travel documents, bank cards and daily medications. Next, you'll want some in-flight entertainment to while away the hours. A thrilling novel and a phone filled with your favourite movies are some great options. If you intend to catch forty winks, a comfy neck pillow and a pair of noise-cancelling headphones will also be useful. Finally, make room for a toothbrush and some facial wipes so you'll step off the plane looking fresh and raring to go.
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 flammable, sharp or explosive. This includes knives, scissors, aerosol cans and bleaching agents. Sports equipment like baseball bats, and items that could harm other people, such as firearms and swords, can't come on board with you either.
What to wear on a flight:
  • The aisles of an aircraft aren't the place for a fashion parade. Layer up with comfortable clothing and choose shoes that are closed-toe, flat and easy to slip on and off.
  • The result of sustained periods of immobility, deep vein thrombosis (DVT) is a blood clot condition that can affect some passengers on long-haul flights. Lower your risks by drinking water, keeping your legs moving and wearing compression socks to help improve your circulation.
How to get through airport security fast when flying to Decatur?
The answer is simple — be prepared. We've rounded up some handy tips and tricks for an easy trip through security. Watch out Decatur, here you come:
  • Be sure to keep your boarding pass and passport within easy reach. They're the first items you'll be asked to show at airport security.
  • Time to strip down. Well kind of. Your belt, coat, keys and other small items, like your earphones, will need to go on a tray through the X-ray machine. Make the whole process easier by removing them before your turn arrives.
  • Your electronic gadgets like laptops and phones will also have to go through the machine to be scanned. Don't worry, you'll be back online before you know it.
  • Remove all gels and liquids from your carry-on luggage. They often need to be sent through the X-ray scanner separately. Each item 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.
  • Slip-on shoes are a great footwear choice as you're less likely to be asked to remove them when passing through security. Boots and heavier-style shoes are usually subjected to extra screening.
  • Airlines won't allow any sharp items or pocket knives to come on board with you. If you need to bring these kinds of items, put them in your checked baggage.
