How to survive the flight to Cadet?
Depending on where you're coming from, your flight to Cadet could be a piece of cake or it could go on forever. Here are some useful hints that will help you start your next big adventure on the right foot.What to pack in your hand luggage:

  • First and foremost, pack in your passport, official ID, credit cards and medications. Next, you'll want some in-flight entertainment to help pass the time. A juicy novel and a phone crammed with your favorite movies are some terrific options. If you hope to catch forty winks, a comfy neck pillow and some noise-canceling headphones will also come in handy. Finally, leave space for a toothbrush and some facial wipes so you'll hop off the plane looking fresh and raring to go.

Do not pack the following items in your hand luggage:

  • Make sure you don't have a Swiss Army knife hiding in your carry-on luggage. Other prohibited items include flammable or explosive goods, such as fuel and fireworks, and gels and liquids in containers larger than 3.4 ounces (100 milliliters).

What to wear on a flight:

  • The main aim is to be as comfortable as you can. Layer up in natural-fiber clothing and remember to pack a sweater just in case you get cold. Opt for well-fitting, flat shoes as it's possible that your feet and ankles will swell a little during the flight. Leave the high heels and heavy boots in your checked baggage.
  • Most travelers have heard about deep vein thrombosis (DVT), a blood clot condition caused by reduced mobility or inactivity. There are plenty of ways to lower your risk. Wear a quality pair of compression socks or tights, stay well hydrated and move your legs and feet. Walk around the cabin when possible or perform some simple exercises in your seat.

How to get through airport security fast when flying to Cadet?
The secret is to be prepared before you get to the security gate. That way, you'll be stepping onto that plane to Cadet before you know it. Follow these tips and get your vacation off to a great start:

  • Security personnel first need to make sure that you have a valid passport and boarding pass before anything else. Have them close by, ready for inspection.
  • Your coat, belt, keys and other small items, like coins, will be required to go through the X-ray machine. Make the whole process easier by removing them as it gets closer to your turn.
  • For just a few moments, you'll have to unplug from technology. Your phone, tablet and any other electronic gadgets will also need to go through the scanner.
  • Want to bring along your favorite hand and nail cream? No problem. As long as the volume is no larger than 3.4 ounces (100 milliliters) and it's stored in a zip-lock bag, it's OK to bring with you in your carry-on baggage.
  • Slip-on shoes are a clever footwear choice as you're less likely to have to remove them when going through security. Boots and other heavy-style shoes are usually subjected to extra screening.
  • Airlines won't allow any sharp items or pocket knives in your hand luggage. If you must bring these kinds of items, pack them safely in your checked baggage.
