Do you have any tips for my flight to Mercer Island?
No matter where you're coming from, flying can be a pleasant experience if you've prepared well. Take a peek at these top travel tips that will help get your Mercer Island vacation started on the right foot. What to pack in your hand luggage:

  • Air travel can be a stress-free experience if you carry the right gear. Firstly, you'll want some toiletry items, such as toothpaste, a toothbrush and some deodorant, a clean pair of socks and a magazine or two. Secondly, find room in your hand luggage for your electronic devices, chargers, your medications and perhaps a quality neck pillow as well. Lastly, and most importantly, don't forget to bring your passport, travel docs and some money.

Do not pack the following items in your hand luggage:

  • Leave all your full-sized bottles of shampoo and conditioner in your checked luggage. Any gels or liquids in your carry-on bag larger than 3.4 ounces (100 millilitres) will be confiscated. Sharp or pointed objects, like your treasured Swiss Army knife, and products which are flammable or explosive, such as aerosol cans, flares and matches, are also not allowed.

What to wear on a flight:

  • The aisles of an airplane aren't the place for a fashion parade. Dress in comfortable layers and choose shoes that are roomy, flat and easy to slip on and off.
  • Deep vein thrombosis (DVT), a blood clot condition caused by lengthy periods of inactivity, can be a risk on long-haul flights. Try to walk around the cabin or do some simple exercises in your seat to improve your circulation.

How to get through airport security fast when flying to Mercer Island?
The secret is to be prepared before you get to the security gate. That way, you'll be stepping onto that plane to Mercer Island in next to no time. Follow these tips and get your vacation off to a great start:

  • Security personnel first need to check that you have a valid ID and travel documents before anything else. Keep them within easy reach.
  • Next up is the X-ray machine. Empty your pockets and remove anything metal that is likely to set off the alarm. This includes things like earphones or headphones, as well as your coat or jacket. They'll all need to go on the X-ray conveyor belt.
  • Your electronic devices like phones and laptops will also have to go through the machine to be scanned. No need to worry though, you'll be back online soon enough.
  • Want to bring along your favourite hand cream? Not a problem. As long as the volume is no larger than 3.4 ounces (100 millilitres) and it's stored in a clear zip-close bag, you can bring it with you on board.
  • Slip-on shoes are a clever footwear choice as you're less likely to have to remove them when going through security. Safety boots and other heavy shoes are usually subjected to extra screening.
  • 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.
