How to survive the flight to South Sioux City?
We’ve rounded up all the info you need to make your flight as enjoyable as possible. Follow our tips and tricks and you’ll be hightailing it through the airport and enjoying South Sioux City before you know it.What to pack in your hand luggage:

  • The secret to having a stress-free travel experience is to pack ahead. First up, the essentials: passport, travel docs, credit cards and any vital medications. Next, bring on board items that’ll help keep you busy, like some electronic gadgets or a good book. You’ll also want to pack your chargers, a quality neck pillow and a pair of noise-cancelling headphones. Finally, don’t forget to chuck in toiletry items like a toothbrush, deodorant and a clean T-shirt.

Do not pack the following items in your hand luggage:

  • Double-check that you don’t have a sharp object lurking in one of the zippers of your carry-on luggage. Other banned items include explosive or flammable products, such as fuel and fireworks, and gels and liquids in containers with a capacity of more than 3.4 ounces (100 milliliters).

What to wear on a flight:

  • Your number one priority is to be as comfortable as possible. Layer up with loose, natural fibers and take a sweater in case it gets cool. Opt for 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 deep vein thrombosis (DVT), a blood clotting condition caused by prolonged periods of inactivity. To avoid this, make the most of every opportunity to walk around the cabin and stretch your legs. Compression socks and tights are another easy way to help minimize this risk.

How to get through airport security fast when flying to South Sioux City?
The trick is to be well organised before you reach security. That way, you’ll be boarding that plane to South Sioux City in no time flat. Follow these helpful tips and get your trip off to a fantastic start:

  • Your boarding pass and travel ID will need to be presented to airport security personnel. Keep them at hand so you don’t have to dig around for them.
  • The X-ray machine is up next. Remove anything metal on you that is likely to beep. This includes items like headphones or earphones, as well as your coat or jacket. They’ll all need to go on the X-ray conveyor belt.
  • For just a few moments, you’ll have to unplug from technology. Your tablet, phone and any other electronic devices will also need to be sent through the scanner.
  • Don’t forget to remove gels and liquids from your hand luggage. They usually need to be sent through the X-ray separately. Each item should be in a container no larger than 3.4 ounces (100 milliliters) and everything must fit in a single quart-size (one litre), clear zip-lock bag.
  • The right choice of footwear can save you several precious minutes. Boots and bulky shoes are often required to be removed and X-rayed separately. Lightweight sneakers usually aren’t.
  • Avoid taking prohibited items in your carry-on bag. If you have any sharp objects like a pocket knife or tools, put them in your checked baggage. They won’t be allowed on board.
