Do you have any tips for my flight to Mountlake Terrace?
We've pulled together all the info you need to make your flight a pleasant experience. Follow our tips and tricks and you'll be hightailing it through the airport and exploring Mountlake Terrace before you know it. What to pack in your hand luggage:

  • The secret to having a great flight experience is to pack ahead. First up, the essentials: passport, official ID, bank cards and vital medications. Next, bring on board items that'll help keep you busy, like your laptop or a good read. It's also wise to bring your chargers, a comfy neck pillow and a pair of headphones. Finally, don't forget to pop in toiletry items like a toothbrush, cleansing wipes and a clean T-shirt.

Do not pack the following items in your hand luggage:

  • Double-check that you don't have sharp objects (like a knife or scissors) hiding in your carry-on luggage. Other restricted items include explosive or flammable goods, such as bleach and fuel, and gels and liquids in containers with a capacity of more than 3.4 ounces (100 millilitres).

What to wear on a flight:

  • The aisles of a plane aren't the place for a fashion parade. Don comfortable layers and pick shoes that are enclosed, flat and easy to slip on and off.
  • The result of sustained periods of inactivity, deep vein thrombosis (DVT) is a blood clotting condition that can affect some passengers on long-distance flights. Lower your risks by drinking water, keeping your legs and ankles moving and wearing compression socks or tights.

How to get through airport security fast when flying to Mountlake Terrace?
As savvy travellers know, the secret is to be organized before you reach airport security. That way, you'll be stepping onto that plane to Mountlake Terrace in next to no time. Follow these tips and get your vacation off to a fantastic start:

  • First things first. Your ID and travel documents will need to be inspected by airport security personnel. Have them easily accessible so you don't hold up the queue.
  • Time to strip down. Well kind of. Your belt, jacket, keys and other contents of your pockets, like your earphones, will need to go on a tray through the X-ray machine. Make the whole process faster by removing them before your turn arrives.
  • Electronic devices like laptops and phones will also need to go on a tray for inspection. No need to worry though, you'll be back online before you know it.
  • Travelling with a new cologne? Not a problem. As long as it's in a container no larger than 3.4 ounces (100 millilitres) and it's stored in a clear zip-lock bag, you're permitted to bring it with you in your carry-on luggage.
  • There's a good chance you'll need to take your shoes off to be X-rayed, so wearing lightweight sneakers is always a wise 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 luggage. They won't be allowed on board and will be confiscated.
