How to get through airport security fast when traveling to St. Mary's
Make your journey to St. Mary’s a little bit easier by following these clever security tips:

  • Airport security will ask to see your passport and boarding pass upon arrival. Store them in an accessible place, so they’re all ready for inspection.
  • You’ll need to put your tunes on pause for a little while. Earphones need to be removed and put in a tub for X-raying. The same goes for items such as coins and keys.
  • Ensure your phone, laptop and other electronic devices are within easy reach. These items need to be sent through the X-ray machine in separate tubs.
  • Lip balm, toothpaste and other toiletry items in cream, liquid or gel form need to be stored in containers no larger than 3.4 ounces (100 milliliters). They must also fit in a 1-quart (1-liter) clear zip-lock plastic bag.
  • Think about your choice of footwear. Slippers are awesome because they’re super easy to slip out of for the airport security checks. Try wearing some on your next flight!
  • Some places have strict quarantine laws. Think about where you’re headed to and whether or not you’re allowed to fly with unpackaged foods.
