Do you have any tips for my flight to St. Ignatius?

  • Wherever you’re coming from, flying can be an enjoyable experience if you come prepared. First of all, pack your passport (or a valid ID), travel documents and medications. Next, throw in some extra in-flight entertainment to help the time fly by. The latest bestseller and a tablet filled with your favorite series are a couple of good options. If you plan to take a short nap, a comfy neck pillow and headphones are also worth squeezing in.
  • There’s a list of items you shouldn’t pack in your carry-on too. Explosives, flammables and sharps are strictly prohibited in the cabin — they often include box cutters, razor blades, aerosol cans and flares. Some sporting equipment, like tennis rackets and baseball bats, also generally can’t go in your hand luggage. Check your airline’s website for details about what you can and can’t bring on board.

What to wear on a flight:

  • Choose comfort before fashion when flying. Layer up and wear natural fabrics as they allow air and moisture to pass through and keep you cool. Cabin temperatures typically get cooler on long-haul flights, so bring a hoodie or similar and always wear sneakers or enclosed shoes.
  • The condition known as deep vein thrombosis (DVT) is a risk on long-haul flights. It’s the result of blood clotting due to inactivity and poor circulation. Walking up and down the aisle and doing leg and foot exercises while seated can prevent it developing. Wearing compression tights or socks can also help to lower your risk.

How can I get a cheap last-minute flight to St. Ignatius?
To get your hands on a cheap, spur-of-the-moment flight to St. Ignatius, it’s important to be flexible. If you can, have a bit of wiggle room with the dates you plan to travel. It’s also wise to leave your options open with your airports, choice of airline, flight times and possible stops or layovers.
Where can I learn more about changing or canceling my flight to St. Ignatius?
Most flights are free to cancel within 24 hours of making the reservation. However, some flights are non-refundable, and you may receive a flight credit from the airline to use for a future booking. For more information, please visit our Customer Service Portal.
