Do you have any tips for my flight to Wentzville?
Depending on where you're coming from, your trip to Wentzville could be completely painless or it could go on forever. Here are some handy travel tips that will help you start your unforgettable escape on a positive note. What to pack in your hand luggage:

  • A plane trip can be a stress-free experience if you bring the right stuff. Firstly, you'll need basic toiletry items, such as a toothbrush and some deodorant, a fresh set of clothes and a good book. Secondly, make room in your hand luggage for your phone and charger, any vital medications and perhaps a proper neck pillow as well. Last, but definitely not least, don't forget to bring your passport, travel docs and some cash.

Do not pack the following items in your hand luggage:

  • While the list of banned items differs between air carriers, the general rule of thumb is avoid carrying anything flammable, sharp or explosive. This includes things like knives, scissors, aerosol cans and flares. Sports equipment like baseball bats, and objects that could harm other people, such as swords and batons, won't be allowed on board either.

What to wear on a flight:

  • Comfort should be your number one priority when deciding what to wear on board. Loose, breathable clothing is a sensible choice, as are flat, enclosed shoes.
  • Deep vein thrombosis (DVT) can pose a risk on long-distance flights. It results from blood clots forming due to poor circulation and inactivity, so do some gentle leg and foot exercises in your seat and consider wearing compression tights or socks.

How to get through airport security fast when flying to Wentzville?
The secret is to be well prepared before you get to the airport security gate. That way, you'll be hopping onto that plane to Wentzville in a flash. Follow these tips and get your trip off to a great start:

  • Be sure to have your ID and boarding pass at hand. They'll be the first things you'll be asked to present to security.
  • Next up is the X-ray machine. Empty your pockets and remove anything that is likely to beep. This includes things like earphones or headphones, as well as bulky coats or jackets. They'll need to be placed on the conveyor belt for screening.
  • All electronic gadgets, including your tablet and phone, will also need to be scanned separately.
  • Any liquids or gels, such as hair oil or hand cream, that you want to take on board must be no larger than 3.4 ounces (100 millilitres). Also, they all must fit inside a quart-size (one litre), clear zip-close bag.
  • Slip-on shoes are a practical footwear choice as you're less likely to have to remove them when passing through security. Boots and other heavy shoes are usually subjected to additional screening.
  • Take all prohibited items out of your carry-on bag. If you have any sharp objects like a pocket knife or tools, pack them safely away in your checked baggage. They won't be allowed in the cabin.
