Do you have any tips for my flight to Saint Louis?
Depending on where you're coming from, your flight to Saint Louis could be completely stress-free or it could drag on forever. We've rounded up some handy tips that will help you start your next big adventure on the right foot. What to pack in your hand luggage:

  • The secret to having an awesome flight experience is to be prepared. So, let's start with the basics: passport, official ID, credit cards and any vital medications. Next, bring on board items that'll help pass the time, like some electronic devices or a magazine. You'll also want to pack your chargers, a quality neck pillow and a pair of noise-cancelling headphones. Last but not least, be sure to pop in toiletry items like a toothbrush, deodorant and a fresh set of clothes.

Do not pack the following items in your hand luggage:

  • Double-check that you don't have sharp objects (like a pocket knife) hiding in your hand luggage. Other prohibited items include explosive or flammable goods, such as aerosol cans and bleach, and gels and liquids in containers with a capacity of more than 3.4 ounces (100 millilitres).

What to wear on a flight:

  • Choose comfort over style. Prepare for temperature changes in the cabin by layering up, and pick closed-toe, flat shoes like sneakers.
  • Most of us have heard about deep vein thrombosis (DVT), a blood clot condition caused by prolonged periods of inactivity. To minimize your risk on board, stay hydrated, consider wearing compression socks or tights and move your legs and feet often.

How to get through airport security fast when flying to Saint Louis?
The answer is — be prepared. We've put together some useful tips for a hassle-free trip through airport security. Watch out Saint Louis, here you come:

  • Your travel documents and passport will need to be presented to airport security. Keep them at hand so you don't hold up the line.
  • The X-ray machine comes next. Remove anything on you that is likely to beep. This includes items like headphones or earphones, as well as heavy jackets or coats. They'll all need to go on the X-ray conveyor belt.
  • For just a few minutes, you'll need to unplug from the digital world. Your laptop, phone and any other electronics will need to be sent through the scanner.
  • Any liquids or gels, such as perfume or hairspray, that you want to bring on board need to be in containers no larger than 3.4 ounces (100 millilitres). Also, they all must fit inside a quart-size (one litre), clear zip-lock bag.
  • The right choice of footwear can save you several minutes. Boots and heavy shoes are often required to be removed and X-rayed separately. Lightweight sneakers are usually not.
  • Airlines won't allow any pocket knives or other sharp items to come on board with you. If you need to bring these kinds of items, pack them in your checked baggage.
