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

  • Wherever you’re heading, flying can be an enjoyable experience if you come prepared. First of all, pack your travel documents, passport and medications. Next, throw in some extra in-flight entertainment to while away the hours. A good read and a tablet filled with your favorite series are a couple of good options. If you plan on catching some sleep, a comfortable neck pillow and earplugs will also come in handy.
  • Don’t forget there’s also a list of prohibited items for your hand luggage which can differ between airlines. Generally, avoid bringing anything sharp, flammable or explosive. This includes things like box cutters, razor blades, flares and aerosol cans. Sporting equipment like baseball bats, and objects that could harm passengers, such as swords and batons, 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 in comfortable clothes and bring a sweater as it can get cool in the cabin on long-haul flights. Enclosed, flat shoes are best for longer journeys.
  • Reduce your risk of developing deep vein thrombosis (DVT), a blood clotting condition which can be caused by sitting for extended periods, by regularly walking around the cabin. Alternatively, do foot and leg exercises in your seat. If you’re at higher risk of developing DVT, consider wearing compression socks.

How can I get a cheap last-minute flight to St. Anthony?
If you want to grab a cheap last-minute flight to St. Anthony, aim to be flexible. If possible, have a little wiggle room with the dates you can fly. It also helps to have some flexibility with your arrival and departure airports, choice of airline, flight times and possible layovers or stops.
Where can I learn more about changing or canceling my flight to St. Anthony?
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.
