How to survive the flight to St. Ignatius?
We’ve rounded up all the info you need to make your flight as pain-free as possible. Follow our tips and you’ll be cruising through the airport and enjoying St. Ignatius in no time at all.What to pack in your hand luggage:

  • First things first, put in your passport, important documents, credit cards and daily medications. Next, you’ll need some in-flight entertainment to while away the time. A thrilling book and a tablet crammed with your favourite shows are some wonderful options. If you plan to catch forty winks, a neck pillow and some earplugs will also be useful. Finally, leave some space for a toothbrush and some facial wipes so you’ll touchdown feeling fresh as a daisy.

Do not pack the following items in your hand luggage:

  • Double-check that you don’t have a sharp object lurking in the bottom of your carry-on luggage. Other restricted items include explosive or flammable products, such as bleach and fuel, and gels and liquids in containers larger than 3.4 ounces (100 milliliters).

What to wear on a flight:

  • The long, narrow aisles of your airplane are not the place for a fashion parade. Layer yourself up with comfortable clothes and remember to bring a sweater as it can get quite cool in the cabin on long-haul flights. Flat, enclosed 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. The good news is there are proven ways to significantly reduce your risk of developing it. Keep your fluids up, get up and walk around the cabin as much as possible and wear compression socks or tights.

How to get through airport security fast when flying to St. Ignatius?

  • Time to strip down. Well sort of. Your coat, belt, keys and other contents of your pockets, like coins, will need to go on a tray through the X-ray machine. Make the whole process faster by removing them as your turn draws near.
  • All your electronic devices, including your phone and laptop, are also required to be separately scanned.
  • Travelling with a new perfume? Not a problem. As long as it’s in a container no larger than 3.4 ounces (100 milliliters) and it’s stored in a clear zip-lock bag, it’s OK to bring with you in your carry-on baggage.
  • Choosing your footwear wisely can save you a few precious minutes. Boots are often required to be removed and separately scanned. Slip-on shoes usually aren’t.
  • Airlines won’t allow any sharp items or pocket knives in your hand luggage. If you need to bring these kinds of items, put them in your checked baggage.
