Do you have any tips for my flight to SeaTac?
Wherever you're coming from, flying can be a seamless experience if you're well prepared. We've compiled a list of handy tips and tricks that will help get your SeaTac vacation started on the right note. What to pack in your hand luggage:

  • A plane ride can be easy if you bring the right stuff. First of all you'll need basic toiletry items, such as a toothbrush and lip balm, a spare pair of socks and a few magazines. Next, make room in your bag for your electronic devices, chargers, any medications and perhaps a proper neck pillow too. Last, but definitely not least, don't forget to bring your passport, travel papers and your credit cards.

Do not pack the following items in your hand luggage:

  • Make sure you don't have a Swiss Army knife lurking in one of the zippers of your carry-on luggage. Other restricted items include flammable or explosive products, like aerosols and matches, and gels and liquids in containers larger than 3.4 ounces (100 millilitres).

What to wear on a flight:

  • You'll want to choose comfort over style. Prepare for temperature changes by dressing in layers, and opt for slightly roomy, flat footwear like slip-ons.
  • Deep vein thrombosis (DVT), a blood clot condition caused by prolonged inactivity, can be a risk on long-haul flights. Try to walk around the cabin and stretch your legs or do some simple exercises in your seat to improve your circulation.

How to get through airport security fast when flying to SeaTac?
It's all about being organized. We've put together some top tips for a stress-free trip through airport security. Look out SeaTac, here you come:

  • Your boarding pass and passport will need to be presented to security personnel. Have them close by so you don't hold up the line.
  • Next up, both you and your carry-on luggage must be X-rayed. To make the process quick and painless, take off anything that might trigger the alarms. Items like your belt, jacket and earphones need to go through the machine.
  • For just a few minutes, you'll have to unplug from technology. Your tablet, phone and any other electronic devices also need to go through the scanner.
  • Any liquids or gels, such as perfume or hand cream, that you want to take 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.
  • There's a chance you'll be required to take your shoes off to be X-rayed, so wearing slip-on sneakers is always a clever idea.
  • Sharp or pointed items can't be taken on board. They'll be confiscated at security, so put them in your checked suitcase.
