Do you have any tips for my flight to SeaTac?
If you're not prepared, travelling can be a real challenge. But there's no need to hit the panic button just yet. Follow these useful tips and enjoy a comfortable start to your getaway in SeaTac. What to pack in your hand luggage:

  • A plane ride can be a great experience if you pack the right stuff. Firstly, you'll want a few basic toiletries, such as lip balm and hand cream, a clean set of clothes and a good read. Secondly, make room in your hand luggage for your mobile phone, a charger, your medications and perhaps a quality neck pillow as well. Lastly, and most importantly, be sure to take your passport, travel documents and some cash.

Do not pack the following items in your hand luggage:

  • Check carefully that you don't have sharp or pointed objects hiding in the bottom of your carry-on luggage. Other prohibited items include flammable or explosive products, such as fuel and matches, and liquids and gels in containers with a capacity of more than 3.4 ounces (100 millilitres).

What to wear on a flight:

  • You'll want to go for comfort over style. Prepare for temperature changes by dressing in layers, and opt for flat, closed-toe shoes like sneakers.
  • Deep vein thrombosis (DVT) is a risk on long-distance flights. It's the result of blood clots forming due to poor circulation and inactivity, so do some gentle foot and leg exercises in your seat and consider wearing compression tights or socks.

How to get through airport security fast when flying to SeaTac?
The secret is to be well organized before you reach the airport security gate. That way, you'll be hopping onto that plane to SeaTac in no time at all. Follow these tips and get your trip off to a terrific start:

  • Have your travel documents and passport within easy reach. They're the first things you'll be asked to show at airport security.
  • Time to strip down. Well kind of. Your belt, jacket, keys and other small items, like your earphones, will be required to go through the X-ray machine. Make the whole process easier by removing them as it gets closer to your turn.
  • For just a few minutes, you'll need to unplug from the digital world. Your tablet, phone and any other electronics will need to go through the scanner.
  • Any liquids or gels, such as toothpaste or perfume, that you want to bring on board must be no greater than 3.4 ounces (100 millilitres). They must also all fit inside a quart-size (one litre), clear zip-close bag.
  • The right choice of footwear can save you several precious minutes. Hiking boots are often required to be removed and X-rayed separately. Lightweight sneakers are usually not.
  • Airlines won't allow any sharp items or pocket knives to come on board with you. If you need to bring these kinds of items, pack them safely in your checked baggage.
