Do you have any tips for my flight to Affton?
We've rounded up all the info you need to make your journey an enjoyable experience. Follow our insider tips and you'll be zooming through airport security and seeing the best of Affton in no time. What to pack in your hand luggage:

  • It's easy --- first, pack your passport, official ID, cash and daily medications. Next, you'll want some in-flight entertainment to while away the time. A juicy novel and a laptop filled with your favourite shows are good options. If you plan to take a quick nap, a neck pillow and some noise-cancelling headphones will also come in handy. Finally, squeeze in a toothbrush and some cleansing wipes so you'll arrive looking and feeling fresh.

Do not pack the following items in your hand luggage:

  • Squeeze all your full-sized bottles of shampoo and hair gel in your checked baggage. Any liquids or gels in your carry-on bag larger than 3.4 ounces (100 millilitres) will be confiscated. Sharp or pointed objects, like your beloved Swiss Army knife, and dangerous products which are explosive or flammable, such as aerosol cans, spray paint and fuels, are also banned.

What to wear on a flight:

  • The aisles of an airplane aren't the place for a fashion parade. Layer up with comfortable clothing and opt for shoes that are flat and easy to take on and off.
  • Caused by prolonged periods of inactivity, deep vein thrombosis (DVT) is a blood clot condition that can affect some passengers during long flights. Lower your risks by drinking water, keeping your legs moving and wearing compression socks to help improve your circulation.

How to get through airport security fast when flying to Affton?
A little pre-planning before your flight can make your trip to Affton quick and painless. Check out our handy hints for a swift journey through security:

  • Keep your passport and boarding pass within easy reach. They're the first items you'll be asked to show at airport security.
  • After that, both you and your carry-on bag must be X-rayed. To speed things up, remove anything that is likely to trigger the alarm. Items such as your belt, coat and earphones need to go through the machine.
  • Electronic devices like phones and laptops will also need to go on a tray to be scanned. No need to worry though, you'll be back online before you know it.
  • Remember to remove liquids and gels from your carry-on luggage. They usually need to be sent through the X-ray separately. Each product should be in a container no larger than 3.4 ounces (100 millilitres) and everything must fit inside a single quart-size (one litre), clear zip-close bag.
  • The right choice of footwear can save you several valuable minutes. Boots are often required to be removed and separately scanned. Lightweight sneakers are usually not.
  • Airlines won't allow any sharp items or pocket knives to come on board with you. If you need to bring these kinds of items, put them in your checked luggage.
