Do you have any tips for my flight to Affton?
We've got the lowdown on how to make your flight as stress-free as possible. Follow our insider tips and you'll be cruising through airport security and exploring Affton in no time flat. What to pack in your hand luggage:
  • A plane trip can be easy if you take the right stuff. Firstly, you'll need toiletry items, such as deodorant and a toothbrush, a spare set of clothes and something to read. Secondly, find a spot in your hand luggage for your laptop, a charger, your important medications and maybe a proper neck pillow too. Lastly, and most importantly, be sure to take your passport, travel documents and some cash.
Do not pack the following items in your hand luggage:
  • While the list of prohibited items can differ between airlines, the general guide to follow is avoid carrying anything sharp, flammable or explosive. This includes tools, metal cutlery, fuels and bleaching agents. Sporting equipment like golf clubs, and objects that could injure passengers, such as pepper spray and firearms, can't come on board with you either.
What to wear on a flight:
  • Comfort should be your highest priority when deciding what to wear on your flight. Loose clothing is a sensible option, as are roomy, closed-toe shoes.
  • Deep vein thrombosis (DVT), a blood clotting condition caused by prolonged periods of inactivity, can be a risk on long-haul flights. Try to walk around the cabin or do some simple exercises in your seat to improve your circulation.
How to get through airport security fast when flying to Affton?
Being prepared before your flight will help make your trip to Affton a piece of cake. Check out our top tips for a speedy journey through security:
  • Airport security personnel first need to determine that you have a valid ID and boarding pass before anything else. Have them ready to show.
  • After that, both you and your carry-on bag must be X-rayed. To speed things up, remove anything that might trigger the alarms. Items such as your coat, belt and headphones need to go through the machine.
  • Your electronic gadgets like phones and laptops will also need to go on a tray to be scanned. Don't worry, you'll be back online soon enough.
  • Can't travel without your favourite hand cream? Not a problem. As long as the volume is no larger than 3.4 ounces (100 millilitres) and it's stored in a zip-close bag, you can bring it with you in your carry-on bag.
  • The right choice of footwear can save you several precious minutes. Boots and heavy shoes are often required to be removed and X-rayed separately. Slip-on shoes are usually not.
  • Airlines won't allow any sharp or pointed objects in the cabin. If you need to bring these kinds of items, pack them in your checked baggage.
