We've rounded up all the info you need to make your journey as pain-free as possible. Follow our tips and you'll be breezing through airport security and discovering St. Ignatius in next to no time. What to pack in your hand luggage:
  • A plane ride can be a pleasure if you carry the right stuff. First things first, you'll need toiletry items, such as deodorant, toothpaste and a toothbrush, a fresh set of clothes and a magazine or two. Secondly, make room in your bag for your phone and charger, medications and perhaps a neck pillow as well. Last, but definitely not least, remember to take your passport, travel documents and some cash.
Do not pack the following items in your hand luggage:
  • While the list of prohibited items differs between airlines, the general guide to follow is nothing sharp, flammable or explosive. This includes screwdrivers, pocket knives, fireworks and fuel. Sports equipment like ice skates, and objects that could injure passengers, such as swords and guns, aren't allowed in the cabin either.
What to wear on a flight:
  • The aisles of an aircraft are no place for a fashion parade. Layer up with comfortable clothing and pick shoes that are enclosed, flat and easy to remove.
  • You're probably aware of deep vein thrombosis (DVT), a blood clotting condition caused by prolonged periods of inactivity. To reduce your risk on board, stay hydrated, consider wearing compression socks or tights and do gentle foot and leg exercises in your seat.
How to get through airport security fast when flying to St. Ignatius?
It's all about being organised. We've compiled some helpful hints for an easy trip through security. Look out St. Ignatius, here you come:
  • Security personnel first need to verify that you have a valid passport and matching boarding pass before anything else. Have them close by, ready for inspection.
  • The X-ray machine comes next. Remove anything on you that is likely to set off the alarm. This includes things like earphones or headphones, as well as your coat or jacket. They'll all need to go on the X-ray conveyor belt.
  • All electronic gadgets, including your phone and laptop, will also need to be scanned separately.
  • Want to bring along your favourite perfume? As long as the volume is no larger than 3.4 ounces (100 millilitres) and it's stored in a clear zip-close bag, it's OK to bring with you in your carry-on luggage.
  • Choosing your footwear wisely can save you several minutes. Boots and bulky shoes are often required to be removed and X-rayed separately. Slip-on sneakers usually aren't.
  • Knives and other sharp items can't be taken on board. They'll be seized at security, so pack them in your checked suitcase.
