Do you have any tips for my flight to St. Peters?
If you're poorly prepared, travelling can be challenging. But don't hit the panic button just yet. Follow these useful tips for a pleasant start to your vacation in St. Peters. What to pack in your hand luggage:

  • First things first, pack your passport, travel documents, cash and medications. Next, you'll want some extra in-flight entertainment to while away the hours. A juicy novel and a phone filled with your favourite movies are some terrific options. If you intend to take a short snooze, a neck pillow and a pair of earplugs will also be useful. Finally, squeeze in a few toiletry items so you'll hop off the plane feeling fresh and raring to go.

Do not pack the following items in your hand luggage:

  • Make sure you don't have sharp objects (like a knife or scissors) hiding in the bottom of your hand luggage. Other restricted items include flammable or explosive substances, such as fuel and matches, and gels and liquids in containers with a capacity of more than 3.4 ounces (100 millilitres).

What to wear on a flight:

  • The aisles of a plane are no place for a fashion parade. Dress in comfortable layers and opt for shoes that are closed-toe, flat and easy to pull on and off.
  • Deep vein thrombosis (DVT), a blood clot condition caused by extended periods of inactivity, can be a risk on long-haul flights. Make a point of walking around the cabin or do some simple exercises in your seat to promote better circulation.

How to get through airport security fast when flying to St. Peters?
A little pre-planning before your flight can make your trip to St. Peters easy and painless. Here are some top tips for a speedy journey past security:

  • Be sure to have your travel documents and passport at hand. They're the first things you'll be asked to show at airport security.
  • The X-ray machine comes next. Empty your pockets and remove anything metal that is likely to set off the alarm. This includes items like headphones or earphones, as well as heavy coats or jackets. They'll all need to go on the X-ray conveyor belt.
  • Electronic devices like laptops and phones will also need to go on a tray for inspection. No need to worry though, you'll be back online in no time.
  • Travelling with a new hand and nail cream? As long as it's in a container no larger than 3.4 ounces (100 millilitres) and it's stored in a clear zip-lock bag, you're permitted to bring it with you in your carry-on bag.
  • There's a possibility that you'll need to remove your shoes for scanning, so wearing slip-on shoes is always a smart idea.
  • Airlines won't allow any sharp items or pocket knives in the cabin. If you must bring these kinds of items, pack them safely in your checked baggage.
