Do you have any tips for my flight to Sioux City?
Wherever you're jetting in from, flying can be an enjoyable experience if you're prepared. We've made a list of handy hints that will help get your Sioux City escape started on the right foot. What to pack in your hand luggage:

  • First of all, put in your passport, official ID, wallet and vital medications. Next, you'll want some entertainment to while away the hours. A juicy novel and a tablet filled with your favourite movies are some terrific options. If you hope to take a short nap, a comfy neck pillow and some earplugs will also come in handy. Finally, find room for a few toiletry items 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 prohibited items differs between airlines, the general guide to follow is nothing flammable, sharp or explosive. This includes things like screwdrivers, blades, aerosol cans and bleaching agents. Sports equipment like baseball bats, and objects that could harm passengers, such as firearms and ammunition, can't come on board with you either.

What to wear on a flight:

  • The aisles of an airplane aren't the place for a fashion parade. Don comfortable layers and pick shoes that are flat, roomy and easy to pull on and off.
  • Caused by sustained periods of immobility, deep vein thrombosis (DVT) is a blood clot condition that can affect passengers on long-haul flights. Reduce the risks by drinking water, keeping your legs moving and wearing compression socks or tights.

How to get through airport security fast when flying to Sioux City?
The answer is — be prepared. We've put together some top tips for an easy trip through airport security. Look out Sioux City, here you come:

  • Your travel ID and boarding pass will need to be inspected by airport security. Keep them at hand to avoid fumbling around for them.
  • Next up is the X-ray machine. Remove anything on you that is likely to set off the alarm. This includes items like earphones or headphones, as well as your coat or jacket. They'll all need to go on the X-ray conveyor belt.
  • Electronic devices like phones and laptops will also have to go on a tray for inspection. Don't worry, you'll be back online before you know it.
  • Don't forget to remove liquids and gels from your hand luggage. They often need to be sent through the X-ray scanner separately. Each product should be no larger than 3.4 ounces (100 millilitres) and everything must fit in a quart-size (one litre), clear zip-lock bag.
  • Slip-on shoes are a great footwear choice as you're less likely to be required to remove them when passing through security. Safety boots and other bulky shoes are usually subjected to extra screening.
  • Airlines will not allow any sharp or pointed objects to come on board with you. If you need to bring these kinds of items, pack them safely in your checked luggage.
