How to survive the flight to St. Louis?
No matter where you’re coming from, flying can be an enjoyable experience if you’re well organized. We’ve compiled a list of essential travel tips that will help get your St. Louis escape started on the right foot.What to pack in your hand luggage:

  • Air travel can be a comfortable experience if you take the right stuff. First things first, you’ll need basic toiletries, such as deodorant, toothpaste and a toothbrush, a clean pair of socks and something to read. Next, find a spot in your bag for your phone and charger, your medications and perhaps a quality neck pillow as well. Lastly, and most importantly, don’t forget to take your passport, travel docs and some cash.

Do not pack the following items in your hand luggage:

  • While the list of restricted items differs between airlines, the general guide to follow is avoid carrying anything flammable, sharp or explosive. This includes things like screwdrivers, pocket knives, fuels and bleaching agents. Sporting equipment like ski poles, and objects that could injure passengers, such as swords and batons, won’t be allowed on board either.

What to wear on a flight:

  • The narrow aisles of your aircraft are no fashion runway. Layer up with comfortable clothing and pack a sweater as it can get quite cool inside the cabin during long-haul flights. Flat, enclosed shoes are also a good choice.
  • The condition known as DVT (deep vein thrombosis) can pose a risk on long-distance flights. It results from blood clotting due to poor circulation and inactivity. Doing leg and foot exercises in your seat helps to prevent this from happening. Wearing a high-quality pair of compression socks is also recommended.

How to get through airport security fast when flying to St. Louis?
As savvy travelers know, the secret is to be organized before you arrive at security. That way, you’ll be stepping onto that plane to St. Louis in no time flat. Follow these tips and get your vacation off to a spectacular start:

  • First things first. Your passport and boarding pass will need to be shown to airport security. Keep them at hand so you don’t hold up the line.
  • Next up is the X-ray machine. Remove anything on you that is likely to beep. This includes items like headphones or earphones, as well as your coat or jacket. They’ll need to be placed on the conveyor belt for screening.
  • All your electronic devices, including your tablet and phone, will also need to be separately scanned.
  • Want to bring along your favorite hand and nail cream? As long as it’s in a container no larger than 3.4 ounces (100 milliliters) and it’s stored in a clear zip-lock bag, you’re allowed to bring it with you in your carry-on baggage.
  • Lightweight sneakers are a clever footwear choice as you’re less likely to be asked to remove them when passing through security. Hiking boots and other bulky shoes are usually subjected to additional screening.
  • Take all prohibited items out of your carry-on bag. If you have any sharp or pointed objects, pack them in your checked baggage. They won’t be allowed on board.
