Do you have any tips for my flight to Maryland Heights?
If you're poorly prepared, air travel can be challenging. But there's no need to worry. Follow these tips and tricks for a hassle-free start to your time in Maryland Heights. What to pack in your hand luggage:

  • Air travel can be easy if you carry the right things. First things first, you'll need basic toiletry items, such as a toothbrush and lip balm, a spare set of clothes and a good read. Secondly, find room in your bag for your phone, tablet and chargers, your important medications and maybe a comfy neck pillow as well. Lastly, and most importantly, remember to bring your passport, travel docs and some money.

Do not pack the following items in your hand luggage:

  • While the list of prohibited items differs between airlines, the general guide to follow is nothing sharp, flammable or explosive. This includes things like tools, metal cutlery, fuels and bleaching agents. Sports equipment like ice skates, and items that could injure passengers, such as firearms and swords, aren't allowed in the cabin either.

What to wear on a flight:

  • Your aim here is to feel as comfortable as possible. Opt for a pair of slip-on shoes, dress in loose, natural fibers and don't forget to bring a sweater in case you get cold in the cabin.
  • Caused by prolonged periods of inactivity, deep vein thrombosis (DVT) is a blood clot condition that can affect passengers during long flights. Lower your risks by staying hydrated, keeping your ankles and legs moving and wearing compression socks to help your circulation.

How to get through airport security fast when flying to Maryland Heights?
The simple answer is — be prepared. We've rounded up some handy tips and tricks for a stress-free trip through airport security. Watch out Maryland Heights, here you come:

  • Have your travel documents and ID close by. They're the first things you'll be asked to present to security.
  • The X-ray machine is up next. Empty your pockets and remove anything that is likely to beep. This includes things like headphones or earphones, as well as bulky coats or jackets. They'll need to be placed on the conveyor belt for screening.
  • For just a few minutes, you'll need to unplug from technology. Your tablet, phone and any other electronics will also need to go through the scanner.
  • Remove all gels and liquids from your carry-on luggage. They often need to be sent through the X-ray machine separately. Each product should be in a container no larger than 3.4 ounces (100 millilitres) and everything must fit in a quart-size (one litre), clear zip-lock bag.
  • Choosing your footwear wisely can save you a few precious minutes. Boots and heavy shoes are often required to be removed and X-rayed separately. Slip-on sneakers are usually not.
  • Avoid taking prohibited items in 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.
