Do you have any tips for my flight to St. Marys?
Depending on where you're coming from, your flight to St. Marys could be as easy as pie or it could drag on forever. We've rounded up some useful travel tips that will help you start your next great adventure on a positive note. What to pack in your hand luggage:
  • It's simple — first, put in your passport, official ID, bank cards and vital medications. Next, you'll want some entertainment to help pass the time. A thrilling novel and a phone filled with your favorite movies are always good options. If you plan to catch up on some sleep, a neck pillow and some noise-canceling headphones will also be useful. Finally, find room for a toothbrush and some cleansing wipes to ensure you arrive looking fresh and raring to go.
Do not pack the following items in your hand luggage:
  • Squeeze all your full-sized bottles of shampoo and conditioner in your checked baggage. Any liquids in your carry-on suitcase larger than 3.4 ounces (100 milliliters) will be confiscated by authorities. Sharp or pointed objects, like a Swiss Army knife, and dangerous goods which are flammable or explosive, such as aerosol cans, spray paint and strong acids, are also not allowed.
What to wear on a flight:
  • You'll want to choose comfort over style. Prepare for temperature changes in the cabin by layering up, and wear easy-to-remove footwear like slip-ons.
  • Deep vein thrombosis (DVT) can pose a risk on long-distance flights. It results from blood clots forming due to poor circulation, so do some gentle leg and foot exercises in your seat and consider wearing compression tights or socks.
How to get through airport security fast when flying to St. Marys?
A little pre-planning before you get to the airport will make your getaway to St. Marys a piece of cake. Read through our useful tips for a stress-free journey past security:
  • Keep your ID and travel documents someplace easily accessible. They're the first items you'll be asked for by airport security.
  • Your jacket, belt, keys and other items in your pocket, like your headphones, will need to go on a tray through the X-ray machine. Make the whole process easier by removing them before your turn arrives.
  • Your electronic gadgets like phones and laptops will also need to go on a tray for inspection. Don't worry though, you'll be back online in no time.
  • Want to bring along your favorite perfume? Not a problem. As long as the volume is no greater than 3.4 ounces (100 milliliters) and it's stored in a zip-close bag, you can bring it with you in your carry-on.
  • It's also likely that you'll need to remove your shoes to be X-rayed, so wearing slip-on sneakers is always a clever idea.
  • Avoid taking prohibited items in your carry-on bag. If you have any sharp objects like a pocket knife or tools, pack them safely away in your checked baggage. They won't be allowed in the cabin.
