How to survive the flight to Doe Run?
Wherever you're coming from, flying can be a pleasurable experience if you've prepared well. Check out these top travel tips that will get your Doe Run escape started on the right foot.What to pack in your hand luggage:

  • The trick to having an awesome flight experience is to pack in advance. Start with the essentials: passport, travel docs, credit cards and any vital medications. Next, take on board items that'll help keep you entertained, like some electronic gadgets or a thrilling novel. You'll also want to bring your chargers, a neck pillow and a pair of earplugs. Last but not least, be sure to squeeze in toiletries like a toothbrush, lip balm and a fresh set of clothes.

Do not pack the following items in your hand luggage:

  • Check carefully that you don't have a Swiss Army knife hiding in one of the compartments of your hand luggage. Other banned items include explosive or flammable goods, such as aerosol cans and fuel, and gels and liquids in containers with a capacity of more than 3.4 ounces (100 milliliters).

What to wear on a flight:

  • The goal here is to make yourself as comfortable as possible. Dress in loose, natural fibers and take a cardigan in case it gets cool in the cabin. Go for a pair of well-fitting, flat shoes as your feet may swell during the flight. Leave the stilettos and heavy boots in your luggage.
  • Caused by sustained periods of immobility, DVT (deep vein thrombosis) is a blood clot condition that can affect passengers during long flights. The great news is there are ways to reduce your risk of developing it. Keep your fluids up, walk up and down the aisles as much as possible and wear compression socks to help improve your circulation.

How to get through airport security fast when flying to Doe Run?
The trick is to be organized before you arrive at airport security. That way, you'll be stepping onto that plane to Doe Run in no time flat. Follow these helpful tips and get your trip off to a flying start:

  • Your passport and travel documents will need to be inspected by security personnel. Have them easily accessible to avoid fumbling around for them.
  • Next up, both you and your hand luggage will be X-rayed. To make the process quick and painless, take off anything that might trigger the alarms. Items like your belt, coat and headphones will be required to go through the machine.
  • All your electronics, including your phone and laptop, must also be separately scanned.
  • Any liquids or gels, such as toothpaste or perfume, that you want to take on board must be no greater than 3.4 ounces (100 milliliters). Also, everything must fit inside a quart-size (one liter), zip-lock bag.
  • Choosing your footwear wisely can save you several precious minutes. Hiking or heavy-style boots are often required to be removed and X-rayed separately. Lightweight sneakers are usually not.
  • Avoid taking prohibited items in your carry-on bag. If you have any sharp or pointed objects, pack them in your checked baggage. They won't be allowed on board.
