Do you have any tips for my flight to Sullivan?
Wherever you're coming from, flying can be an enjoyable experience if you prepare well enough. Check out these handy travel tips that will help get your Sullivan escape started on the right note. What to pack in your hand luggage:
  • The trick to having a pain-free flight experience is to pack ahead. So, let's start with the essentials: passport, travel docs, bank cards and daily medications. Next, bring on board items that'll help keep you entertained, like some electronic gadgets or a thrilling book. It's also smart to bring your chargers, a quality neck pillow and a pair of headphones. Finally, don't forget to chuck in toiletry items like a toothbrush, lip balm and a spare change of clothes.
Do not pack the following items in your hand luggage:
  • While the list of banned items can differ between airlines, the general guide to follow is nothing flammable, sharp or explosive. This includes tools, metal cutlery, fuel and fireworks. Sporting equipment like hockey sticks, and items that could injure passengers, such as pepper spray and guns, are also banned from the cabin.
What to wear on a flight:
  • The aisles of an aircraft aren't the place for a fashion parade. Layer up with comfortable clothing and opt for shoes that are flat and easy to remove.
  • Most travellers have heard about deep vein thrombosis (DVT), a blood clotting condition caused by long periods of sitting. To lower your risk on board, drink plenty of water, consider wearing compression socks and keep your legs and feet moving.
How to get through airport security fast when flying to Sullivan?
It's simple — be prepared. We've compiled some useful tips for a hassle-free trip through security. Watch out Sullivan, here you come:
  • Be sure to keep your boarding pass and ID within easy reach. They'll be the first things you'll be asked for by security.
  • Time to strip down. Well sort of. Your coat, belt, keys and other small items, like coins, will be required to go through the X-ray machine. Make your life easier by removing them as it gets closer to your turn.
  • For just a few minutes, you'll have to unplug from technology. Your tablet, phone and any other electronic devices must also be sent through the scanner.
  • Travelling with your favourite perfume? No problem. As long as it's in a container no larger than 3.4 ounces (100 millilitres) and it's stored in a clear zip-close bag, you can keep it with you on board.
  • Lightweight sneakers are a great footwear choice as you're less likely to have to remove them when going through security. Hiking boots and other heavy-style shoes are often subjected to extra screening.
  • Sharp items are not allowed in the cabin. They'll be seized at security, so pack them safely away in your checked suitcase.
