Do you have any tips for my flight to Seattle?
Depending on where you're coming from, your flight to Seattle could be no sweat at all or it could go on forever. We've put together some tips that will help you start your next great adventure on a positive note. What to pack in your hand luggage:
  • First of all, pack in your passport, travel docs, credit cards and medications. Next, you'll need some in-flight entertainment to while away the time. A thrilling novel and a laptop filled with your favourite movies are some terrific options. If you plan to catch more than just forty winks, a neck pillow and a pair of earplugs will also be useful. Finally, leave space for a toothbrush and some cleansing wipes so you'll hop off the plane feeling fresh and raring to go.
Do not pack the following items in your hand luggage:
  • Double-check that you don't have a sharp object hiding in your hand luggage. Other banned items include explosive or flammable substances, like aerosols and matches, and liquids and gels in containers larger than 3.4 ounces (100 millilitres).
What to wear on a flight:
  • Your aim here is to feel as comfortable as possible. Pick flat, closed-toe shoes, dress in loose, breathable clothing and don't forget to bring a pullover in case you get chilly in the cabin.
  • Caused by sustained periods of immobility, deep vein thrombosis (DVT) is a blood clotting condition that can affect some passengers on long-haul flights. Lower your risks by drinking water, keeping your feet and legs moving and wearing compression socks to help your circulation.
How to get through airport security fast when flying to Seattle?
It's easy — be prepared. We've put together some top tips for an easy trip through airport security. Look out Seattle, here you come:
  • Security personnel first need to establish that you have a valid passport and matching boarding pass before you're allowed to proceed any further. Have them in your hand, ready for inspection.
  • Your jacket, belt, keys and other small items, like coins, will be required to go through the X-ray machine. Make the whole process faster by removing them before your turn.
  • For just a few moments, you'll have to unplug from technology. Your phone, laptop and any other electronics will need to be sent through the scanner.
  • Any liquids or gels, such as hair oil or hand cream, 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), clear zip-close bag.
  • Slip-on shoes are a great footwear choice as you're less likely to have to remove them when passing through security. Safety boots and other heavy shoes are often subjected to additional screening.
  • Airlines will not allow any pocket knives or other sharp items in the cabin. If you must bring these kinds of items, pack them in your checked luggage.
