How to survive the flight to Saint Mary's City?
Wherever you're jetting in from, flying can be a pleasurable experience if you're prepared. Check out these handy travel tips that will help get your Saint Mary's City vacation started on the right foot.What to pack in your hand luggage:

  • Air travel can be a comfortable experience if you take the right gear. First of all you'll need toiletry items, such as deodorant, toothpaste and a toothbrush, a fresh change of clothes and a magazine or two. Next, find room in your hand luggage for your phone and charger, your medications and maybe a cozy neck pillow as well. Last, but definitely not least, don't forget to take your passport, travel papers and your bank cards.

Do not pack the following items in your hand luggage:

  • Squeeze all your full-sized bottles of shampoo and conditioner in your checked luggage. Any liquids or gels in your carry-on suitcase larger than 3.4 ounces (100 milliliters) won't be allowed on. Sharp objects, like a pocket knife, and dangerous goods which are flammable or explosive, such as flares, bleaching agents and fireworks, are also restricted.

What to wear on a flight:

  • Your number one priority is to make yourself as comfortable as possible. Dress in loose, natural fibers and remember to pack a sweater just in case you get chilly. Always opt for roomy, flat shoes as your feet may swell during the journey. Leave the stilettos and chunky boots in your main luggage.
  • The condition by the name of DVT (deep vein thrombosis) can pose a risk on long-distance flights. It's the result of blood clots forming due to poor circulation and inactivity. Doing foot and leg exercises while seated helps to prevent this occurring. Wearing a good-quality pair of compression socks also helps reduce the risk.

How to get through airport security fast when flying to Saint Mary's City?
The answer is simple — be organized. We've rounded up some helpful hints for an easy trip through airport security. Look out Saint Mary's City, here you come:

  • Your passport and boarding pass will need to be shown to security personnel. Keep them someplace accessible to avoid fumbling around for them.
  • Next up, both you and your carry-on bag will be X-rayed. To speed things up, take off anything that is likely to trigger the alarm. Items such as your jacket, belt and earphones will be required to go through the machine.
  • All your electronics, including your tablet and phone, will also need to be scanned separately.
  • Remove liquids and gels from your hand luggage. They often need to be sent through the X-ray scanner separately. Each item should be in a container no larger than 3.4 ounces (100 milliliters) and everything must fit in a single quart-size (one liter), clear zip-lock bag.
  • There's a possibility that you'll be required to take your shoes off to be X-rayed, so wearing lightweight sneakers is always a wise idea.
  • Pocket knives and other sharp items can't be taken on board. They'll be confiscated at security, so put them in your checked baggage.
