Do you have any tips for my flight to St. Leonard?
Depending on where you're coming from, your flight to St. Leonard could be as easy as pie or it could go on forever. We've pulled together some useful travel tips that will help you start your next unforgettable escape on a positive note. What to pack in your hand luggage:

  • It's easy — first, pack in your passport, travel documents, wallet and vital medications. Next, you'll want some extra in-flight entertainment to while away the time. A thrilling novel and a laptop filled with your favourite movies are some wonderful options. If you hope to catch a few z's, a quality neck pillow and a pair of noise-cancelling headphones will also come in handy. Finally, make room for a toothbrush and some cleansing wipes so you'll step off the plane 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 gels or liquids in your carry-on bag larger than 3.4 ounces (100 millilitres) won't be allowed on. Pointed or sharp objects, like your precious Swiss Army knife, and dangerous goods which are explosive or flammable, such as flares, bleaching agents and strong acids, are also not allowed.

What to wear on a flight:

  • Your top priority is to feel as comfortable as possible. Choose flat, closed-toe shoes, dress in loose, natural-fibre clothing and don't forget to bring a sweater in case it gets chilly in the cabin.
  • Deep vein thrombosis (DVT) is a risk on long-distance flights. It's the result of blood clots forming due to inactivity and poor circulation, so do some gentle leg and foot exercises in your seat and consider wearing compression socks.

How to get through airport security fast when flying to St. Leonard?
A little pre-planning before your flight will help make your getaway to St. Leonard quick and painless. Below you'll find some useful tips for a stress-free journey past security:

  • First things first. Your ID and travel documents will need to be shown to airport security personnel. Have them easily accessible to avoid fumbling around for them.
  • Your belt, coat, keys and other small items, like coins, will need to go on a tray through the X-ray machine. Make the whole process faster by removing them before your turn.
  • Electronic devices like laptops and phones will also have to go on a tray to be scanned. Don't worry, you'll be back online before you know it.
  • Can't travel without your favourite perfume? Not a problem. As long as the volume is no greater than 3.4 ounces (100 millilitres) and it's stored in a clear zip-close bag, you can keep it with you in your carry-on bag.
  • Lightweight sneakers are a good footwear choice as you're less likely to be required to remove them when going through security. Boots and other bulky shoes are often subjected to additional screening.
  • Avoid taking prohibited items in your carry-on bag. If you have any sharp or pointed objects, pack them safely away in your checked luggage. They won't be allowed on board.
