Do you have any tips for my flight to Seattle?
If you're poorly prepared, travelling can be testing. But there's no need to worry. Follow these helpful hints and enjoy a stress-free start to your time in Seattle. What to pack in your hand luggage:

  • Travelling on a plane can be a stress-free experience if you've got all the right things. Firstly, you'll want a few basic toiletry items, such as lip balm and hand cream, a clean pair of socks and a good read. Next, find room in your carry-on bag for your mobile phone, a charger, your medications and perhaps a blow-up neck pillow too. Last, but definitely not least, be sure to bring your passport, travel papers and your credit cards.

Do not pack the following items in your hand luggage:

  • Pack all your full-sized bottles of hair gel and hairspray in your checked baggage. Any gels or liquids in your carry-on bag larger than 3.4 ounces (100 millilitres) will be confiscated. Pointed or sharp objects, like your trusty pocket knife, and dangerous goods which are explosive or flammable, such as aerosol cans, flares and fuels, are also banned.

What to wear on a flight:

  • Your goal here is to be as comfortable as you can. Go for slip-on footwear, dress in loose, natural fibers and don't forget to take a pullover in case it gets cold in the cabin.
  • It's likely you've heard about deep vein thrombosis (DVT), a blood clot condition caused by long periods of sitting. To lower your risk on board, stay hydrated, consider wearing compression socks and keep your legs and feet moving.

How to get through airport security fast when flying to Seattle?
The secret is to be well prepared before you arrive at airport security. That way, you'll be stepping onto that plane to Seattle in next to no time. Follow these helpful tips and get your trip off to a fantastic start:

  • Security personnel first need to check that you have a valid ID and boarding pass before anything else. Keep them close by.
  • After that, both you and your carry-on bag must be X-rayed. To make the process quick and painless, take off anything that is likely to set the alarm off. Personal belongings like your coat, belt and headphones need to go through the machine.
  • For just a few moments, you'll have to unplug from the digital world. Your tablet, phone and any other electronic gadgets must also be sent through the scanner.
  • Any gels or liquids, such as shampoo or hairspray, that you want to bring on board need to be in containers no greater than 3.4 ounces (100 millilitres). Also, everything must fit inside a quart-size (one litre), zip-lock bag.
  • Lightweight sneakers are a good footwear choice as you're less likely to be asked to remove them when passing through security. Big boots and other heavy shoes are often subjected to additional screening.
  • Sharp items such as knives and scissors are not allowed in the cabin. They'll be confiscated at security, so pack them safely away in your checked baggage.
