Do you have any tips for my flight to St. Peters?
We've pulled together all the info you need to make your journey an enjoyable experience. Follow our tips and you'll be speeding through airport security and discovering St. Peters in next to no time. What to pack in your hand luggage:

  • The secret to having a pain-free flight experience is to be prepared. So, let's start with the essentials: passport, travel documents, cash and vital medications. Next, bring items that'll help pass the time, like some electronic devices or a good read. It's also wise to pack your chargers, a neck pillow and a pair of earphones. And of course, don't forget to pop in toiletries like a toothbrush, cleansing wipes and a fresh change of clothes.

Do not pack the following items in your hand luggage:

  • While the list of banned items differs between air carriers, the general rule to follow is avoid carrying anything sharp, flammable or explosive. This includes things like tools, metal cutlery, fuels and bleaching agents. Sporting equipment like ice skates, and objects that could harm passengers, such as firearms and swords, can't come on board with you either.

What to wear on a flight:

  • Your main aim is to feel as comfortable as you can. Go for shoes that are easy to slip on and off, dress in loose, natural-fibre clothing and don't forget to take a pullover in case it gets cold in the cabin.
  • Deep vein thrombosis (DVT) can pose a risk on long-distance flights. It results from blood clots forming due to poor circulation and inactivity, so do some gentle foot and leg exercises in your seat and consider wearing compression socks or tights.

How to get through airport security fast when flying to St. Peters?
A little pre-planning before you arrive at the airport will help make your trip to St. Peters easy and painless. We've compiled some handy tips and tricks for a swift journey past security:

  • Security personnel first need to determine that you have a valid ID and boarding pass before anything else. Have them close by, ready for inspection.
  • The X-ray machine is up next. Remove anything metal on you that is likely to set off the scanner's alarm. This includes items like headphones or earphones, as well as heavy jackets or coats. 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 phone, laptop and any other electronic gadgets also need to go through the scanner.
  • Can't travel without your favourite cologne? No problem. As long as the volume is no larger than 3.4 ounces (100 millilitres) and it's stored in a zip-lock bag, you're allowed to bring it with you in your carry-on.
  • Choosing your footwear wisely can save you several valuable minutes. Hiking or heavy-style boots are often required to be removed and X-rayed separately. Lightweight sneakers are usually not.
  • Airlines will not 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.
