How to survive the flight to St. Peters?
Wherever you’re coming from, flying can be a pleasant experience if you’ve prepared well enough. Check out these handy hints that will help get your St. Peters escape started on the right note.What to pack in your hand luggage:

  • Firstly, and most importantly, pack your passport, travel docs, bank cards and medications. Next, you’ll need some in-flight entertainment to help pass the time. A juicy novel and a laptop crammed with your favourite movies are some fantastic options. If you plan to take a quick nap, a quality neck pillow and some noise-cancelling headphones will also be useful. Finally, leave some space for a toothbrush and some cleansing wipes so you’ll step off the plane looking fresh and ready to go.

Do not pack the following items in your hand luggage:

  • While the list of banned items can differ between air carriers, the general rule of thumb is nothing flammable, sharp or explosive. This includes things like screwdrivers, blades, fireworks and fuel. Sporting equipment like bows and arrows, and items that could harm passengers, such as firearms and swords, aren’t allowed in the cabin either.

What to wear on a flight:

  • The aisles of your airplane are no fashion runway. Wear comfortable clothes and remember to bring a cardigan as it tends to get cool in the cabin during long-haul flights. Enclosed, flat shoes are also a good choice.
  • The result of sustained periods of immobility, deep vein thrombosis (DVT) is a serious condition that can affect some passengers during long flights. But the great news is there are ways to lower your risk of developing it. Stay well hydrated, walk around the cabin whenever possible and wear compression socks to help improve your circulation.

How to get through airport security fast when flying to St. Peters?
The answer is — be prepared. We’ve pulled together some top tips for an easy trip through airport security. Look out St. Peters, here you come:

  • Keep your boarding pass and passport at hand. They’re the first things you’ll be asked to present to airport security.
  • After that, both you and your hand luggage will be X-rayed. To make the process quick and painless, take off anything that is likely to trigger the alarm. Personal belongings such as your belt, coat and headphones need to go through the machine.
  • All your electronic devices, including your laptop and phone, must also be scanned separately.
  • Don’t forget to remove gels and liquids from your carry-on luggage. They usually need to be sent through the X-ray machine separately. Each product should be no larger than 3.4 ounces (100 milliliters) and everything must fit in a single quart-size (one litre), clear zip-lock bag.
  • It’s also possible you’ll need to take your shoes off to be X-rayed, so wearing slip-on sneakers is always a smart idea.
  • Airlines will not allow any pocket knives or other sharp items in your carry-on luggage. If you must bring these kinds of items, check them in.
