How to survive the flight to St. Louis?
Wherever you’re coming from, flying can be a pleasant experience if you’re prepared. We’ve put together a list of essential travel tips that will get your St. Louis escape started on the right foot.What to pack in your hand luggage:

  • A plane ride can be a pleasure if you’ve got all the right gear. Firstly, you’ll want a few basic toiletries, such as a toothbrush and hairbrush, a fresh set of clothes and something to read. Next, find a spot in your bag for your electronic gadgets, chargers, your important medications and perhaps a neck pillow as well. Lastly, remember to take your passport, travel documents and some money.

Do not pack the following items in your hand luggage:

  • Pack all your full-sized bottles of shampoo and hair gel in your checked luggage. Any gels or liquids in your carry-on suitcase larger than 3.4 ounces (100 milliliters) will be confiscated by authorities. Sharp or pointed objects, like a pocket knife, and dangerous goods which are explosive or flammable, such as flares, bleaching agents and strong acids, are also prohibited.

What to wear on a flight:

  • The main aim is to make yourself as comfortable as you can. Layer yourself up in natural-fiber clothing and remember to pack a cardigan in case it gets cold in the cabin. Go for a pair of roomy, flat shoes as your feet may swell during the flight. Leave the high heels and hiking boots in your luggage.
  • A serious condition called deep vein thrombosis (DVT) can pose a risk on long-distance flights. It’s the result of blood clots forming due to poor circulation. Walking around the cabin and doing regular leg and foot exercises while seated helps to prevent this from happening. Wearing a pair of compression socks also helps reduce the risk.

How to get through airport security fast when flying to St. Louis?
Being prepared before you get to the airport can make your trip to St. Louis easy and painless. Below you’ll find some handy tips for a stress-free journey through security:

  • First things first. Your boarding pass and travel ID will need to be shown to airport security personnel. Keep them someplace accessible so you don’t have to dig around for them.
  • The X-ray machine is up next. Remove anything on you that is likely to set off the alarm. This includes items like earphones or headphones, as well as heavy jackets or coats. They’ll all need to go on the X-ray conveyor belt.
  • All your electronic devices, including your phone and tablet, will also need to be separately scanned.
  • Traveling with your favorite perfume? Not a problem. As long as the volume is no larger than 3.4 ounces (100 milliliters) and it’s stored in a clear zip-lock bag, it’s OK to bring with you in your carry-on.
  • Slip-on shoes are a great footwear choice as you’re less likely to have to remove them when passing through security. Big boots and heavier-style shoes are usually subjected to extra screening.
  • Airlines won’t allow any sharp items or pocket knives in your carry-on luggage. If you must bring these kinds of items, pack them safely in your checked baggage.
