How to survive the flight to Mercer Island?
Depending on where you’re coming from, your trip to Mercer Island could be a piece of cake or it could drag on forever. Here are some handy travel tips that will help you start your next unforgettable escape on the right foot.What to pack in your hand luggage:

  • The secret to having an amazing flight experience is to plan ahead. So, let’s start with the basics: passport, boarding pass, credit cards and medications. Next, bring on board items that’ll help while away those hours, like your laptop or a thrilling book. It’s also wise to bring your chargers, a comfy neck pillow and a pair of earplugs. And of course, don’t forget to squeeze in toiletries like a toothbrush, lip balm and a spare change of clothes.

Do not pack the following items in your hand luggage:

  • Put all your full-sized bottles of hair gel and hairspray in your checked baggage. Any liquids in your carry-on suitcase larger than 3.4 ounces (100 milliliters) will be confiscated by security. Pointed or sharp objects, like your trusty Swiss Army knife, and products which are flammable or explosive, such as aerosol cans, flares and gasoline, are also prohibited.

What to wear on a flight:

  • Comfort should be your main priority when deciding what to wear on your flight. Consider your footwear choice with care too, as swelling of the feet and ankles can be a side effect of flying. Roomy, closed-toed shoes are always a sensible way to go.
  • Most travelers are aware of DVT (deep vein thrombosis), a blood clotting condition caused by long periods of inactivity. There are numerous ways to mitigate your risk. Wear a good-quality pair of compression socks, drink plenty of water and remember to keep your legs and feet moving. Walk the aisles of the cabin or perform exercises in your seat.

How to get through airport security fast when flying to Mercer Island?
It’s easy — be prepared. We’ve rounded up some top tips for a speedy trip through airport security. Look out Mercer Island, here you come:

  • Be sure to have your boarding pass and ID close by. They’re the first items you’ll be asked to show at airport security.
  • Your coat, belt, keys and other items in your pocket, like your headphones, will be required to go through the X-ray machine. Make your life easier by removing them as it gets closer to your turn.
  • For just a few minutes, you’ll need to unplug from technology. Your tablet, phone and any other electronics must also go through the scanner.
  • Any liquids or gels, such as perfume or hand cream, that you want to bring on board need to be in containers no larger than 3.4 ounces (100 milliliters). Also, they all must fit inside a quart-size (one liter), clear zip-close bag.
  • It’s also possible you’ll need to remove your shoes to be X-rayed, so wearing lightweight sneakers is always a clever idea.
  • Take all prohibited items out of your carry-on bag. If you have any sharp or pointed objects, put them in your checked suitcase. They won’t be allowed on board.
