Do you have any tips for my flight to Des Peres?
Depending on where you're coming from, your trip to Des Peres could be a piece of cake or it could go on forever. We've rounded up some handy travel tips that will help you start your unforgettable escape on a positive note. What to pack in your hand luggage:

  • Travelling on a plane can be a pleasure if you've got all the right gear. Firstly, you'll want some toiletry items, such as deodorant and a toothbrush, a spare set of clothes and a good book. Secondly, find room in your hand luggage for your electronic gadgets, chargers, your medications and maybe a blow-up neck pillow too. Last, but definitely not least, don't forget to bring your passport, travel docs and some money.

Do not pack the following items in your hand luggage:

  • While the list of banned items differs between airlines, the general rule to follow is avoid carrying anything sharp, flammable or explosive. This includes box cutters, razor blades, fuels and bleaching agents. Sports equipment like baseball bats, and objects that could injure passengers, such as swords and guns, are also banned from the cabin.

What to wear on a flight:

  • The aisles of an aircraft are no place for a fashion parade. Dress in comfortable layers and choose shoes that are enclosed, flat and easy to pull on and off.
  • The result of sustained periods of inactivity, deep vein thrombosis (DVT) is a blood clot condition that can affect passengers during long-haul flights. Reduce the risks by drinking water, keeping your legs and feet moving and wearing compression socks or tights.

How to get through airport security fast when flying to Des Peres?
It's simple --- be prepared. We've put together some helpful hints for a stress-free trip through security. Look out Des Peres, here you come:

  • Airport security personnel first need to check that you have a valid passport and matching boarding pass before anything else. Keep them within easy reach.
  • Next up, both you and your carry-on luggage will be X-rayed. To make the process quick and painless, remove anything that might trigger the alarms. Items like your coat, belt and earphones will be required to go through the machine.
  • Your electronic gadgets like phones and laptops will also have to go on a tray to be scanned. Don't worry, you'll be back online in no time.
  • Any liquids or gels, such as perfume or hand cream, that you want to take on board must be no greater than 3.4 ounces (100 millilitres). Also, everything must fit inside a quart-size (one litre), zip-lock bag.
  • Lightweight sneakers are a good footwear choice as you're less likely to be required to remove them when going through security. Big 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 or pointed objects, put them in your checked baggage. They won't be allowed on board.
